Classification: CPC G | IPC G

Claim 3:
4. The system of claim 1, wherein training the machine learning model further comprises:
initializing, by the processor, a set of internal parameters of the machine learning model at random,
identifying, by the processor, a respective training attribute vector and a respectively corresponding authentication technique annotation in the training dataset,
feeding, by the processor, the respective training attribute vector to the machine learning model,
producing a training output based on the respective training attribute vector,
computing, by the processor, a cross-entropy between the training output and the respective authentication technique annotation, and
applying, by the processor, the set of internal parameters to the machine learning model based on the cross-entropy via backpropagation,
wherein the training output is based on the respective training attribute vector; and
wherein the set of internal parameters applied to the machine learning model is based on the cross-entropy via backpropagation.
