Title: System, method, and computer program product for implementing a generative adversarial network to determine activations

Description:
BACKGROUND 
     1. Field 
     This disclosure relates generally to systems, devices, products, apparatus, and methods that are used for implementing a general adversarial network (GAN) and, in one particular embodiment, to a system, method, and product for implementing a hybrid deep neural network model to determine whether an individual would have an activation in a group. 
     2. Technical Considerations 
     Machine learning may be a field of computer science that uses statistical techniques to provide a computer system with the ability to learn (e.g., to progressively improve performance of) a task with data without the computer system being explicitly programmed to perform the task. In some instances, a machine learning model may be developed based on a set of data so that the machine learning model may perform a task (e.g., a task associated with a prediction) with regard to the set of data. 
     In some instances, a machine learning model, such as a predictive machine learning model, may be used to make a prediction regarding a risk or an opportunity based on data. A predictive machine learning model may be used to analyze a relationship between the performance of a unit based on data associated with the unit and one or more known features of the unit. The objective of the predictive machine learning model may be to assess the likelihood that a similar unit will exhibit the performance of the unit. In some instances, a predictive machine learning model may be used as a fraud detection model. For example, predictive machine learning models may perform calculations based on data associated with payment transactions to evaluate the risk or opportunity of a payment transaction involving a customer, in order to guide a decision of whether to authorize the payment transaction. 
     In some instances, a customer may have account activity with multiple businesses (e.g., multiple merchants). For example, an account of the customer may be involved in one or more transactions involving a customer associated with an account (e.g., a credit card account, a debit card account, and/or the like). The one or more transactions may each have similar characteristics (e.g., the one or more transactions may be associated with a price, a time at which the transaction was initiated, and/or the like). However, a financial institution and/or a merchant may be unable to accurately determine an alignment between the account and the merchant in regard to subsequent activity on (e.g., a future transaction involving) the account by a customer with that merchant. For example, the financial institution and/or the merchant may be unable to accurately determine whether the user will conduct a payment transaction that involves the merchant within a time period based on the account activity. Accordingly, the financial institution and/or the transaction service provider may transmit offers to the customer that are ineffective at encouraging the customer to conduct a payment transaction. By transmitting offers that are ineffective, network resources and/or processing resources may be wasted as compared to transmitting a smaller number of offers that are effective. 
     SUMMARY 
     Accordingly, disclosed are systems, devices, products, apparatus, and/or methods for implementing a generative adversarial network to determine a merchant activation.

Hence, specific dimensions and other physical characteristics related to the embodiments or aspects of the embodiments disclosed herein are not to be considered as limiting unless otherwise indicated. 
     No aspect, component, element, structure, act, step, function, instruction, and/or the like used herein should be construed as critical or essential unless explicitly described as such. Also, as used herein, the articles “a” and “an” are intended to include one or more items, and may be used interchangeably with “one or more” and “at least one.” Furthermore, as used herein, the term “set” is intended to include one or more items (e.g., related items, unrelated items, a combination of related and unrelated items, and/or the like) and may be used interchangeably with “one or more” or “at least one.” Where only one item is intended, the term “one” or similar language is used. Also, as used herein, the terms “has,” “have,” “having,” or the like are intended to be open-ended terms. Further, the phrase “based on” is intended to mean “based at least partially on” unless explicitly stated otherwise. 
     As used herein, the terms “communication” and “communicate” may refer to the reception, receipt, transmission, transfer, provision, and/or the like of information (e.g., data, signals, messages, instructions, commands, and/or the like). For one unit (e.g., a device, a system, a component of a device or system, combinations thereof, and/or the like) to be in communication with another unit means that the one unit is able to directly or indirectly receive information from and/or send (e.g., transmit) information to the other unit. This may refer to a direct or indirect connection that is wired and/or wireless in nature. Additionally, two units may be in communication with each other even though the information transmitted may be modified, processed, relayed, and/or routed between the first and second unit. For example, a first unit may be in communication with a second unit even though the first unit passively receives information and does not actively send information to the second unit. As another example, a first unit may be in communication with a second unit if at least one intermediary unit (e.g., a third unit located between the first unit and the second unit) processes information received from the first unit and sends the processed information to the second unit. In some non-limiting embodiments, a message may refer to a network packet (e.g., a data packet and/or the like) that includes data. 
     As used herein, the terms “issuer,” “issuer institution,” “issuer bank,” or “payment device issuer” may refer to one or more entities that provide accounts to individuals (e.g., users, customers, and/or the like) for conducting payment transactions such as credit payment transactions and/or debit payment transactions. For example, an issuer institution may provide an account identifier, such as a primary account number (PAN), to a customer that uniquely identifies one or more accounts associated with that customer. In some non-limiting embodiments, an issuer may be associated with a bank identification number (BIN) that uniquely identifies the issuer institution. As used herein, the term “issuer system” may refer to one or more computer systems operated by or on behalf of an issuer, such as a server executing one or more software applications. For example, an issuer system may include one or more authorization servers for authorizing a transaction. 
     As used herein, the term “account identifier” may include one or more types of identifiers associated with an account (e.g., a PAN associated with an account, a card number associated with an account, a payment card number associated with an account, a token associated with an account, and/or the like). In some non-limiting embodiments, an issuer may provide an account identifier (e.g., a PAN, a token, and/or the like) to a user (e.g., an account holder) that uniquely identifies one or more accounts associated with that user. The account identifier may be embodied on a payment device (e.g., a physical instrument used for conducting payment transactions, such as a payment card, a credit card, a debit card, a gift card, and/or the like) and/or may be electronic information communicated to the user that the user may use for electronic payment transactions. In some non-limiting embodiments, the account identifier may be an original account identifier, where the original account identifier was provided to a user at the creation of the account associated with the account identifier. In some non-limiting embodiments, the account identifier may be a supplemental account identifier, which may include an account identifier that is provided to a user after the original account identifier was provided to the user. For example, if the original account identifier is forgotten, stolen, and/or the like, a supplemental account identifier may be provided to the user. In some non-limiting embodiments, an account identifier may be directly or indirectly associated with an issuer institution such that an account identifier may be a token that maps to a PAN or other type of account identifier. Account identifiers may be alphanumeric, any combination of characters and/or symbols, and/or the like. 
     As used herein, the term “token” may refer to an account identifier of an account that is used as a substitute or replacement for another account identifier, such as a PAN. Tokens may be associated with a PAN or other original account identifier in one or more data structures (e.g., one or more databases) such that they may be used to conduct a payment transaction without directly using an original account identifier. In some non-limiting embodiments, an original account identifier, such as a PAN, may be associated with a plurality of tokens for different individuals or purposes. In some non-limiting embodiments, tokens may be associated with a PAN or other account identifiers in one or more data structures such that they can be used to conduct a transaction without directly using the PAN or the other account identifiers. In some examples, an account identifier, such as a PAN, may be associated with a plurality of tokens for different uses or different purposes. 
     As used herein, the term “merchant” may refer to one or more entities (e.g., operators of retail businesses) that provide goods, services, and/or access to goods and/or services, to a user (e.g., a customer, a consumer, a customer of a merchant, and/or the like) based on a transaction such as a payment transaction. As used herein, the term “merchant system” may refer to one or more computer systems operated by or on behalf of a merchant, such as a server executing one or more software applications.

     In some non-limiting embodiments, computer-implemented systems, methods, and computer program products for generating a machine learning model to classify an account based on merchant activation are disclosed. For example, a computer-implemented method may include providing, during a training procedure and with at least one processor, an input to a generator network of a generative adversarial network (GAN); generating, with at least one processor, an output of the generator network based on the input, wherein the output comprises a generated dataset, wherein the generated dataset comprises a first plurality of sets of values for each of a plurality of features and the first plurality of sets of values for each of the plurality of features comprises data associated with a first plurality of payment transactions conducted using a plurality of accounts and involving a plurality of merchants; providing, during the training procedure and with at least one processor, the output of the generator network as an input to a discriminator network of the GAN; providing, during the training procedure and with at least one processor, a training dataset as an input to the discriminator network of the GAN, wherein the training dataset comprises a second plurality of sets of values for each of the plurality of features and the second plurality of sets of values for each of the plurality of features comprises data associated with a second plurality of payment transactions conducted using the plurality of accounts and involving the plurality of merchants; updating, during the training procedure and with at least one processor, the generator network of the GAN based on a first output of the discriminator network of the GAN having a label that indicates whether a set of values of each of the plurality of features is a real set of values or a fake set of values; and updating, during the training procedure and with at least one processor, the discriminator network of the GAN based on a second output of the discriminator network of the GAN having a label that indicates whether a selected account of the plurality of accounts is going to conduct a first payment transaction with a selected merchant of the plurality of merchants. 
     In this way, non-limiting embodiments of the present disclosure may accurately determine an alignment between an account and a merchant in regard to subsequent activity on (e.g., future transactions) the account by a customer with that merchant. For example, financial institutions and/or merchants may be able to accurately determine whether a user will conduct a payment transaction that involves the financial institutions and/or merchants within a time period based on the account activity. Accordingly, the financial institutions and/or the merchants may transmit offers to customers that are effective at encouraging the customers to conduct a payment transaction. Additionally, or alternatively, the financial institutions and/or the transaction service providers may forego transmitting offers to customers that would be ineffective at encouraging the customers to conduct the payment transaction. By transmitting offers that are effective, network resources and/or processing resources may be conserved as compared to transmitting a larger number of offers that include offers to customers that would be ineffective at encouraging the customers to conduct payment transactions. Further, financial institutions and/or merchants may forego processing fraudulent payment transactions (e.g., merchant systems may forego transmitting transaction data associated with payment transactions to transaction service provider systems, financial institutions may forego authorizing payment transactions, and/or the like). For example, a selected merchant and/or financial institution associated with the selected merchant may determine to forego permitting a payment transaction to be processed based on determining that an account involved in the payment transaction was not selected from a plurality of accounts to conduct a first payment transaction with the selected merchant. As a result, network resources and/or processing resources may be conserved.

     In some non-limiting embodiments, the discriminator network may include a fifth dense layer comprising a plurality of nodes (e.g., a fourth hidden layer comprising a plurality of nodes). For example, the fifth dense layer (e.g., fourth hidden layer) may include 16 nodes (e.g., 2 4  nodes). Additionally or alternatively, each node may include an activation function (e.g., ReLU function, sigmoid function, hyperbolic tangent function, and/or the like). For example, each node may have a ReLU function as the activation function thereof. In some non-limiting embodiments, the fifth dense layer may be fully connected to the fourth dense layer. 
     In some non-limiting embodiments, the discriminator network may include a sixth dense layer comprising at least one node (e.g., a first output layer comprising at least one node). For example, the sixth dense layer (e.g., first output layer) may include one node (e.g., corresponding to the first output and/or the like). Additionally or alternatively, the node may include an activation function (e.g., ReLU function, sigmoid function, hyperbolic tangent function, and/or the like). For example, the node may have a sigmoid function as the activation function thereof. In some non-limiting embodiments, the sixth dense layer may be fully connected to the fifth dense layer. 
     In some non-limiting embodiments, the discriminator network may include a seventh dense layer comprising at least one node (e.g., a second output layer comprising at least one node). For example, the seventh dense layer (e.g., second output layer) may include one node (e.g., corresponding to the second output and/or the like). Additionally or alternatively, the node may include an activation function (e.g., ReLU function, sigmoid function, hyperbolic tangent function, and/or the like). For example, the node may have a sigmoid function as the activation function thereof. In some non-limiting embodiments, the seventh dense layer may be fully connected to the fifth dense layer. 
     As shown in  FIG.  3   , at step  306 , process  300  may include providing a second input to the discriminator network. For example, transaction service provider system  102  may provide a training dataset as a second input to the discriminator network. In some non-limiting embodiments, such (second) input may be provided (e.g., by transaction service provider system  102 ) to the discriminator network during a training procedure. 
     In some non-limiting embodiments, the training dataset may include a plurality of feature vectors, and each feature vector may include a set of values for a plurality of features that are included in the feature vector. In one example, a set of values for the plurality of features may include account data associated with an account that conducted a plurality of payment transactions involving a plurality of merchants. In some non-limiting embodiments, the plurality of features of each feature vector in the training dataset is the same or similar to the plurality of features of each feature vector in a generated dataset (e.g., a generated dataset that is generated using the generator network). 
     In some non-limiting embodiments, the second plurality of payment transactions may include real payment transactions. Additionally or alternatively, the plurality of features of the training dataset may include the first number of features. In some non-limiting embodiments, the discriminator network may include an input node for each feature of the first number of features (e.g., each feature of the training dataset). 
     In some non-limiting embodiments, at least one output of the discriminator network may be generated. For example, transaction service provider system  102  may generate at least one of a first output, a second output, any combination thereof, and/or the like of the discriminator network based on the input(s) (e.g., first input, second input, any combination thereof, and/or the like). In some non-limiting embodiments, the output(s) may include a first output having a (first) label that indicates whether a set of values of each of the plurality of features is a real set of values or a fake set of values. Additionally or alternatively, the output(s) may include a second output having a (second) label that indicates whether a selected account of the plurality of accounts is going to conduct a payment transaction (e.g., first payment transaction) with a selected merchant of the plurality of merchants. 
     In some non-limiting embodiments, the first output may include a single bit or Boolean value. For example, the first output (e.g., bit or Boolean value) may be 1 or “True,” respectively, if the discriminator network determines (e.g., predicts) that the plurality of features is a real set of values, and 0 or “False” otherwise (or vice versa). In some non-limiting embodiments, the first output may include a categorical value. For example, the first output may be “Real” or “R” if the discriminator network determines (e.g., predicts) that the plurality of features is a real set of values, and “Fake” or “F” otherwise. In some non-limiting embodiments, the first output may include a numerical value associated with a probability (e.g., determined, predicted, and/or the like by the discriminator network) that the plurality of features is real (or a probability that the plurality of features is fake). For example, such numerical value may be a number between 0 and 1, between 0 and 100, and/or the like. 
     In some non-limiting embodiments, the second output may include a single bit or Boolean value. For example, the second output (e.g., bit or Boolean value) may be 1 or “True,” respectively, if the discriminator network determines (e.g., predicts) that the selected account is going to conduct a payment transaction (e.g., first payment transaction) with the selected merchant, and 0 or “False” otherwise (or vice versa). In some non-limiting embodiments, the second output may include a categorical value. For example, the first output may be “Active,” “Activation,” or “A” if the discriminator network determines (e.g., predicts) that the selected account is going to conduct a payment transaction (e.g., first payment transaction) with the selected merchant, and “Non Active,” “Non Activation,” or “N” otherwise. In some non-limiting embodiments, the second output may include a numerical value associated with a probability (e.g., determined, predicted, and/or the like by the discriminator network) that the selected account is going to conduct a payment transaction (e.g., first payment transaction) with the selected merchant. For example, such numerical value may be a number between 0 and 1, between 0 and 100, and/or the like. 
     In some non-limiting embodiments, the plurality of features (e.g., of the generated dataset, the training dataset, and/or the like) may include the first number of features. Additionally or alternatively, the output(s) (e.g., first and second outputs and/or the like) of the discriminator network may include a third number of features (e.g., one feature for the first output, one feature for the second output, and/or the like). In some non-limiting embodiments, the generator network may include an input node for each feature of the first number of features (e.g., each feature of the generated dataset, the training dataset, and/or the like). Additionally or alternatively, the generator network may include an output node for each feature of the third number of features (e.g., each feature of the output(s) of the discriminator network). 
     As shown in  FIG.  3   , at step  308 , process  300  may include updating the generator network. For example, transaction service provider system  102  may update the generator network based on a first output of the discriminator network and/or a (first) label that indicates whether a set of values of each of the plurality of features is a real set of values or a fake set of values. In some non-limiting embodiments, such updating may be performed (e.g., by transaction service provider system  102 ) during a training procedure. 
     In some non-limiting embodiments, transaction service provider system  102  may determine at least one (first) feedback value based on the first output and a label of the respective input (e.g., a label that indicates whether the plurality of features is actually a real set of values or a fake set of values). For example, the (first) feedback value may be an error value (e.g., a prediction error, a contrastive loss, and/or the like) based on the first output and the label. Additionally or alternatively, transaction service provider system  102  may update the generator network (e.g., update the weights thereof and/or the like) based on the feedback value(s) (e.g., using back propagation and/or the like). 
     In some non-limiting embodiments, during the training procedure, transaction service provider system  102  may implement a dropout of a portion of the nodes of at least one of the first dense layer, the second dense layer, the third dense layer, the fourth dense layer, the fifth dense layer, any combination thereof, and/or the like of the generator network. For example, transaction service provider system  102  may implement a dropout of 30% (e.g., of the nodes) at each of the first dense layer, the second dense layer, the third dense layer, the fourth dense layer, and the fifth dense layer of the generator network. In some non-limiting embodiments, a dropout may include randomly dropping out (e.g., ignoring, disabling, disconnecting, and/or the like) nodes during training (e.g., each training iteration and/or the like). For example, such a dropout may allow for regularization, reduction of overfitting, and improvement of generalization error and/or the like. 
     In some non-limiting embodiments, during the training procedure, transaction service provider system  102  may implement a batch normalization of at least one of the first dense layer, the second dense layer, the third dense layer, the fourth dense layer, the fifth dense layer, any combination thereof, and/or the like of the generator network. For example, transaction service provider system  102  may implement a batch normalization at each of the first dense layer, the second dense layer, the third dense layer, the fourth dense layer, and the fifth dense layer of the generator network. In some non-limiting embodiments, a batch normalization may include normalization of the input and/or output values of each node by adjusting and/or scaling the activations of each node. 
     As shown in  FIG.  3   , at step  310 , process  300  may include updating the discriminator network. For example, transaction service provider system  102  may update the discriminator network based on a second output of the discriminator network and/or a (second) label that indicates whether a selected account of the plurality of accounts is going to conduct a first payment transaction with a selected merchant of the plurality of merchants. Additionally or alternatively, transaction service provider system  102  may update the discriminator network (further) based on the first output of the discriminator network and/or a (first) label that indicates whether a set of values of each of the plurality of features is a real set of values or a fake set of values. In some non-limiting embodiments, such updating may be performed (e.g., by transaction service provider system  102 ) during a training procedure. 
     In some non-limiting embodiments, transaction service provider system  102  may determine at least one (second) feedback value based on the second output and a label of the respective input (e.g., that indicates whether a selected account of the plurality of accounts is actually going to conduct a first payment transaction with a selected merchant of the plurality of merchants). For example, the (second) feedback value may be an error value (e.g., a prediction error, a contrastive loss, and/or the like) based on the second output and the label. Additionally or alternatively, transaction service provider system  102  may update the discriminator network (e.g., update the weights thereof and/or the like) based on the feedback value(s) (e.g., using back propagation and/or the like). 
     In some non-limiting embodiments, during the training procedure, transaction service provider system  102  may implement a dropout of a portion of the nodes of at least one of the first dense layer, the second dense layer, the third dense layer, the fourth dense layer, the fifth dense layer, any combination thereof, and/or the like of the discriminator network. For example, transaction service provider system  102  may implement a dropout of 30% (e.g., of the nodes) at each of the first dense layer, the second dense layer, the third dense layer, the fourth dense layer, and the fifth dense layer of the discriminator network. In some non-limiting embodiments, a dropout may include randomly dropping out (e.g., ignoring, disabling, disconnecting, and/or the like) nodes during training (e.g., each training iteration and/or the like). For example, such a dropout may allow for regularization, reduction of overfitting, and improvement of generalization error and/or the like. 
     In some non-limiting embodiments, during the training procedure, transaction service provider system  102  may implement a batch normalization of at least one of the first dense layer, the second dense layer, the third dense layer, the fourth dense layer, the fifth dense layer, any combination thereof, and/or the like of the discriminator network. For example, transaction service provider system  102  may implement a batch normalization at each of the first dense layer, the second dense layer, the third dense layer, the fourth dense layer, and the fifth dense layer of the discriminator network. In some non-limiting embodiments, a batch normalization may include normalization of the input and/or output values of each node by adjusting and/or scaling the activations thereof. 
     In some non-limiting embodiments, during the training procedure, the discriminator network of the GAN may be updated (e.g., optimized and/or the like) based on a formula (e.g., by transaction service provider system  102 ). For example, the formula may include a value of recall for the discriminator network. For the purpose of illustration, recall may be defined as follows:
 
Recall=TP/(TP+FN)
 
wherein TP may represent a number of true positive predictions based on an output of the discriminator corresponding to a label (e.g., ground truth label and/or the like) of a set of values of a plurality of features, and/or FN may represent a number of false negative predictions based on an output of the discriminator not corresponding to a label (e.g., ground truth label and/or the like) of a set of values of a plurality of features.
 
     In some non-limiting embodiments, at least one further input may be provided to the discriminator network. For example, after the discriminator network is trained (e.g., after the training procedure), transaction service provider system  102  may provide at least one further input to the discriminator network. Additionally or alternatively, transaction service provider system  102  may obtain an output (e.g., from the discriminator network based on the further input) that indicates whether an account is going to conduct a first payment transaction with a merchant of the plurality of merchants. 
     In some non-limiting embodiments, transaction service provider system  102  may provide a training dataset as an input to a gradient boosting machine learning model (e.g., Extreme Gradient Boosting (XGBoost) model and/or the like), a collaborative filtering model (e.g., Neural Collaborative Filtering (NCF) model and/or the like), or any combination thereof. In some non-limiting embodiments, the training dataset may include a plurality of feature vectors and transaction service provider system  102  may determine a probability score for each feature vector of the training dataset using the gradient boosting machine learning model, the collaborative filtering model, or a combination thereof. In some non-limiting embodiments, the probability score is a score that indicates a probability that an account associated with a feature vector is going to conduct a first payment transaction with a merchant associated with that feature vector. Transaction service provider system  102  may initialize an output of the discriminator network to be equal to a highest probability score of the probability scores of the plurality of feature vectors. In some non-limiting embodiments, the highest probability score is based on a recall for the discriminator network. In some non-limiting embodiments, transaction service provider system  102  may optimize the discriminator network of the GAN using the highest probability score as the initial output of the discriminator network. 
     For the purpose of illustration, transaction service provider system  102  may provide the randomly generated data (e.g., the random vector and/or the like) as an input to an XGBoost machine learning model and an NCF machine learning model. In some non-limiting embodiments, an output of the machine learning model(s) may be provided (e.g., by transaction service provider system  102 ) as input to the generator network. For example, the output of at least one of a gradient boosting machine learning model (e.g., XGBoost model and/or the like), a neural collaborative filtering (NCF) model, or any combination thereof, may be provided as input to the generator network. For the purpose of illustration, transaction service provider system  102  may provide the output of the XGBoost machine learning model and a NCF machine learning model as the input to the generator network. 
     Referring now to  FIGS.  4 A- 4 D ,  FIGS.  4 A- 4 D  are diagrams of an implementation  400  of a process (e.g., process  300 ) for implementing a GAN to determine a merchant activation. One or more of the functions described with respect to the process may be performed (e.g., completely, partially, and/or the like) by transaction service provider system  102 . In some non-limiting embodiments, one or more of the steps of the process may be performed (e.g., completely, partially, and/or the like) by another device or a group of devices separate from and/or including transaction service provider system  102  such as, for example, user device  104 , merchant system  106 , issuer system  108 , and/or acquirer system  110 . 
     As illustrated in  FIGS.  4 A- 4 D , implementation  400  may include generator network  400   a  and discriminator network  400   b  that are the components of a GAN. In some non-limiting embodiments, the model architecture of generator network  400   a  may include first dense layer  412 , second dense layer  414 , third dense layer  416 , and fourth dense layer  418 . In some non-limiting embodiments, generator network  400   a  may be the same or similar to a generator network as described herein. In some non-limiting embodiments, discriminator network  400   b  may include first dense layer  426 , second dense layer  428 , third dense layer  432 , and fourth dense layer  434 . In some non-limiting embodiments, discriminator network  400   b  may be the same or similar to a discriminator network, as described herein. 
     As shown by reference number  405  in  FIG.  4 A , transaction service provider system  102  may provide input to generator network  400   a . For example, transaction service provider system  102  may provide random noise data  408  as the input to generator network  400   a . In some non-limiting embodiments, generator network output  422  of generator network  400   a  may be based on random noise data  408 . For example, transaction service provider system  102  may provide random noise data  408  as an input to first dense layer  412  of generator network  400   a . In some non-limiting embodiments, an output of first dense layer  412  (e.g., an output of first dense layer  412  based on random noise data  408 ) may be provided as an input to second dense layer  414 , an output of second dense layer  414  may be provided as an input to third dense layer  416 , and an output of third dense layer  416  may be provided as an input to fourth dense layer  418 . In some non-limiting embodiments, an output of fourth dense layer  418  may include generator network output  422 . 
     In some non-limiting embodiments, generator network output  422  may include a plurality of feature vectors and each of the feature vectors represent a payment transaction conducted that involves an account of a customer. In some non-limiting embodiments, the plurality of feature vectors of generator network output  422  may be similar to a plurality of feature vectors included in training dataset  424 . For example, the plurality of feature vectors of generator network output  422  may include values for a plurality of features, where the plurality of features are the same as the plurality of features of the plurality of feature vectors of training dataset  424 . In some non-limiting embodiments, the values for the plurality of features in generator network output  422  are generated by transaction service provider system  102  using generator network  400   a . In some non-limiting embodiments, the plurality of feature vectors in generator network output  422  are generated by transaction service provider system  102  using generator network  400   a  and are labeled by transaction service provider system  102  as having real values or fake values. For example, transaction service provider system  102  may generate the plurality of feature vectors in generator network output  422  using generator network  400   a  based on random noise data  408  and transaction service provider system  102  may label each feature vector as having a real set of values or a fake set of values. 
     As shown by reference number  410  in  FIG.  4 B , transaction service provider system  102  may provide inputs to discriminator network  400   b . For example, transaction service provider system  102  may provide generator network output  422  and training dataset  424  as inputs to discriminator network  400   b . In some non-limiting embodiments, outputs (e.g., discriminator network first output  436  and discriminator network second output  438 ) of discriminator network  400   b  may be based on generator network output  422  and training dataset  424 . For example, transaction service provider system  102  may provide generator network output  422  and training dataset  424  as an input to first dense layer  426  of discriminator network  400   b . In some non-limiting embodiments, an output of first dense layer  426  (e.g., an output of first dense layer  412  based on random noise data  408 ) may be provided as an input to second dense layer  428 , an output of second dense layer  428  may be provided as an input to third dense layer  432 , and an output of third dense layer  432  may be provided as an input to fourth dense layer  434 . In some non-limiting embodiments, an output of fourth dense layer  434  may include discriminator network first output  436  and discriminator network second output  438 . 
     In some non-limiting embodiments, training dataset  424  may include a plurality of feature vectors and the plurality of feature vectors may each include a plurality of features. The values of the plurality of features may include account data associated with one or more accounts at an account level and/or a merchant level. The account data may include an account identifier, a merchant identifier, and/or a rating (e.g., account 123x may have a rating of “0” assigned to a merchant “A”; account 123x may have a rating of “1” assigned to a merchant “B”, account 123x may have a rating of “1” to a merchant “C”, account 456x may have a rating of “0” to the merchant “A”, and/or the like). The rating may include an indication of whether the account associated with a feature vector will have an activation with a merchant (e.g., a merchant activation) associated with a merchant identifier included in the feature vector within a time interval. 
     Additionally or alternatively, the account data may include data associated with one or more merchants. For example, account data may include account level data that may include a total transaction amount of an account in a merchant category code (MCC) during a time interval, a total transaction amount of an account involving a merchant during a time interval, and/or a total number of transactions conducted by an account involving a merchant during a time interval. Additionally or alternatively, account data may include merchant level data that may include a total transaction amount of all accounts in a dataset in an MCC during a time interval, a total transaction amount of all accounts in a dataset involving a merchant during a time interval, and/or a total number of transactions conducted by all accounts in a dataset involving a merchant during a time interval. 
     In some non-limiting embodiments, discriminator network first output  436  may include a plurality of feature vectors that have a label for each feature vector of the plurality of feature vectors. The label may indicate whether an account associated with (e.g., included in) that feature vector is going to conduct a first payment transaction with a merchant associated with (e.g., included in) that feature vector. In some non-limiting embodiments, the label may indicate whether the account associated with the feature vector is going to conduct a first payment transaction with the merchant associated with the feature vector within a time interval (e.g., a predetermined time interval, a predetermined time interval based on the model architecture of discriminator network  400   b , a predetermined time interval based on the model architecture of generator network  400   a , and/or the like). For example, the label may indicate whether the account is going to conduct a first payment transaction with the merchant within a six month time interval (e.g., a six month time interval from a date on which the label was generated). In some non-limiting embodiments, the labels for the plurality of feature vectors included in discriminator network first output  436  are generated by transaction service provider system  102  using discriminator network  400   b  and are generated by transaction service provider system  102 . For example, transaction service provider system  102  may generate the labels for the plurality of feature vectors in discriminator network first output  436  using discriminator network  400   b  based on training dataset  424  and/or generator network output  422  and transaction service provider system  102  may label each feature vector to indicate whether the account associated with the feature vector is going to conduct a first payment transaction with the merchant associated with the feature vector within a time interval. 
     In some non-limiting embodiments, discriminator network second output  438  may include a plurality of feature vectors that have a label for each feature vector of the plurality of feature vectors. The label may indicate whether a set of values included in each feature vector is a real set of values or a fake set of values. In some non-limiting embodiments, the labels for the plurality of feature vectors included in discriminator network second output  438  are generated by transaction service provider system  102  using discriminator network  400   b . For example, transaction service provider system  102  may generate the labels for the plurality of feature vectors in discriminator network second output  438  using discriminator network  400   b  based on training dataset  424  and/or generator network output  422  and transaction service provider system  102  may label each feature vector to indicate whether a set of values included in each feature vector is a real set of values or a fake set of values. 
     As shown by reference number  415  in  FIG.  4 C , transaction service provider system  102  may update generator network  400   a . For example, transaction service provider system  102  may update generator network  400   a  based on discriminator network first output  436 . For example, transaction service provider system  102  may update generator network  400   a  based on a plurality of feature vectors included in discriminator network first output  436  that each have a label that indicates whether a set of values included in each feature vector is a real set of values or a fake set of values. In some non-limiting embodiments, transaction service provider system  102  may update the weights and/or bias terms associated with one or more nodes of generator network  400   a  based on whether the plurality of feature vectors included in discriminator network first output  436  were correctly labeled as having a real set of values or a fake set of values. 
     As further shown by reference number  420  in  FIG.  4 C , transaction service provider system  102  may update discriminator network  400   b . For example, transaction service provider system  102  may update discriminator network  400   b  based on discriminator network first output  436  and training dataset  424 . In some non-limiting embodiments, transaction service provider system  102  may compare the labels of the plurality of feature vectors (e.g., a plurality of labels that indicate whether an account associated with a feature vector of the plurality of feature vectors is going to conduct a first payment transaction with a merchant associated with that feature vector) included in the discriminator network first output  436  to the labels of the plurality of feature vectors included in training dataset  424  and transaction service provider system  102  may determine whether the plurality of feature vectors included in the discriminator network first output  436  were labelled correctly. Transaction service provider system  102  may update discriminator network  400   b  based on determining that one or more feature vectors of the plurality of feature vectors included in discriminator network first output  436  were not labelled correctly. 
     Additionally or alternatively, transaction service provider system  102  may update discriminator network  400   b  based on discriminator network second output  438  and generator network output  422  and training dataset  424 . For example, transaction service provider system  102  may compare the labels of the plurality of feature vectors (e.g., a plurality of labels that indicate whether each feature vector of the plurality of feature vectors includes a set of values that is a real set of values or a fake set of values) included in discriminator network second output  438  to the labels of the plurality of feature vectors included in generator network output  422  and the labels of the plurality of feature vectors included in training dataset  424  and transaction service provider system  102  may determine whether the plurality of feature vectors included in discriminator network second output  438  were labelled correctly. Transaction service provider system  102  may update discriminator network  400   b  based on determining that one or more feature vectors of the plurality of feature vectors included in discriminator network second output  438  were not labelled correctly. 
     As shown by reference number  425  in  FIG.  4 D , transaction service provider system  102  may determine whether an account will have a merchant activation with a merchant. For example, transaction service provider system  102  may provide an input to discriminator network  400   b  after transaction service provider system  102  updated discriminator network  400   b . In some non-limiting embodiments, the input may include a dataset that includes a feature vector with a set of values of a plurality of features. Transaction service provider system  102  may generate discriminator network first output  438  based on the input to discriminator network  400   b . In some non-limiting embodiments, discriminator network first output  438  may include a label (e.g., a rating) that indicates whether an account associated with the feature vector is going to conduct a first payment transaction with a merchant associated with the feature vector within a time interval.
