## Title
Online content classifier which updates a classification score based on a count of labeled data classified by machine deep learning

## Abstract

Embodiments are directed towards online content classification that includes training a machine learning system. A batch of data items may be randomly selected from unlabeled test data. The batch of data items may be communicated to a client computer enabling a user to label each data item based on the contents of each data item. These labeled data items may be employed to train the machine learning system. While a classification result score is less than a threshold value, iteration may be performed to train the machine learning system. For each iteration another batch of data items may be selected from the unlabeled test data. This batch of data items may be classified using the machine learning system. The batch of classified data items may be communicated back to the client computer to be labeled by the user.

## Background
TECHNICAL FIELD
The present invention relates generally to classification of content using machine learning, and more particularly, but not exclusively to reducing the amount of test data that must be labeled by a user.
BACKGROUND
Increasingly, machine learning is being employed for automatically classifying data. Often data may be classified by associating it with one or more labels that correspond to various features of the data. For example, an image classifiers may be arranged to classify images of animals based on the type of animal shown in a given image. In this example, labels may be defined for the type of animal (e.g., sheep, tiger, whale, and so on). Also, in some cases, labels may be defined for various properties of data. Going back to the animal example, labels may be defined such as, mammal, reptile, bird, carnivore, or the like. In many cases, machine learning systems used for classifying data need to be trained using sample data that is correctly labeled. If the classifier is trained using sufficiently and correctly labeled sample data, it may be enabled to correctly classify provided data based on its training. In some cases, many correctly labeled sample data examples must be provided to properly train the classifier. Labeling the sample data may require an expert or other user to manually assign labels to each sample data. In some cases, it may be very time consuming and/or labor intensive to generate the large number of label sample data examples that may be required to train a classifier. Thus, it is with respect to these considerations and others that the invention has been made.

As used herein, the term “machine learning system” refers to computer systems that may be used for classifying input data, pattern recognition, making predictions based on input data, identifies features and/or relationships in data, or the like. While there are many different types of machine learning systems, a common feature is that machine learning systems require training to learn to perform their task. The details of the training process may vary depending on the type of machine learning system, but often it entails providing known/understood test data to the machine learning system and evaluating its success and/or failures at performing the desired tasks (e.g., classifying and/or categorizing the data). These evaluation results are then provided to the machine learning system which will adapt its internal systems based on the evaluations. This process may continue until the machine learning system has “learned” to produce satisfactory results. Various well-known machine learning systems may include, artificial neural networks, deep learning neural networks, convolutional neural networks, adaptive regularization of weights, or the like, or combination thereof.
As used herein the term “machine deep learning system” refers to a machine learning system that comprises one or more deep learning architectures, such as, deep neural networks, convolutional deep neural networks, or the like.
Briefly stated, embodiments are directed towards online content classification that includes training a machine learning system. In at least one of the various embodiments, the machine learning system may include a feature extractor, an online classifier, or the like. In at least one of the various embodiments, a batch of data items may be randomly selected from unlabeled test data. In at least one of the various embodiments, the data items may be different types, such as, images, documents, text documents, audio, financial data, or human speech, or the like. In at least one of the various embodiments, the configuration and/or one or more of the components of the machine learning system may be optimized for a particular type of data.
In at least one of the various embodiments, the batch of data items may be communicated to a client computer enabling a user of the client computer to label each data item based on the contents of each data item. In at least one of the various embodiments, the labeled data items may be employed to train the machine learning system.
In at least one of the various embodiments, while a classification result score is less than a threshold value, additional steps may be iteratively performed to training the machine learning system. Also, in at least one of the various embodiments, the value of the threshold for the classification result score may be defined based on the particular application that the machine learning system is being used for, and/or the type of the test data that is being used. In at least one of the various embodiments, for each iteration another batch of data items may be randomly selected from the remainder of the unlabeled test data. This batch of data items may be classified using the machine learning system that may be partially trained during each iteration of labeled data items.
In at least one of the various embodiments, the batch of classified data items may be communicated back to the client computer. In at least one of the various embodiments, this may enable the user to label each classified data item based on whether the content of each classified data item has been classified correctly by the machine learning system. In at least one of the various embodiments, scoring each classified data item may include grouping the correctly classified data items into one group and grouping incorrectly classified data items into another group. In at least one of the various embodiments, each classified data item may be labeled automatically using another machine vision system.
In at least one of the various embodiments, the labeled data items may be communicated back to the machine learning system where the labeled data items may be used to further train the machine learning system. In at least one of the various embodiments, the classification result score may be updated based on how the user labeled data items. For example, the classification result score may be increased as the number of classification mistakes that were corrected is reduced.
In at least one of the various embodiments, if the training sessions are complete (e.g., the classification result score is high enough) the machine learning system may be used to classify live data.
In at least one of the various embodiments, user interfaces used for labeling the test data item may include at least two workspaces. In at least one of the various embodiments, one workspace may be arranged to display the data items that were classified correctly and the other workspace may be arranged to display the data items that may be classified classified incorrectly.

At decision block 508, in at least one of the various embodiments, if the results of the classifying the current unlabeled data batch is below a defined threshold, control may flow to block 510; otherwise, control may flow to block 512.
In at least one of the various embodiments, the threshold value may vary depending on the type of data being classified and/or the application. Not all types of data or type of applications (e.g., the purpose behind the classification) require the same level of accuracy. Accordingly, in at least one of the various embodiments, configuration information and/or user input may be used for determining the threshold value for determining success.
At block 510, in at least one of the various embodiments, since the accuracy threshold is not reached, the current batch may be labeled by a user and submitted back to the online classification system to be used to further train the system to improve its classification results.

In at least one of the various embodiments, the initial batch of items may be unlabeled if the online classification system is untrained. Accordingly, the user may label the data items according to category/classification that may be of interest. For example, if the online classification system is arranged to determine if an image includes one or more alpacas, the user may label the batch items to indicate if they includes an image of an alpaca. In at least one of the various embodiments, a client computer, such as, client computer 200, may be arranged to display (or play) the data items so the user may label the items if they match the category of interest.

At decision block 612, in at least one of the various embodiments, if the results of the classifying the current unlabeled data batch is below a defined threshold, control may loop back to block 604; otherwise, control may be returned to a calling process.
In at least one of the various embodiments, the threshold value may vary depending on the type of data being classified and/or the application. Not all types of data or type of applications (e.g., the purpose behind the classification) require the same level of accuracy. Accordingly, in at least one of the various embodiments, configuration information and/or user input may be used for determining the threshold value for determining success.
In at least one of the various embodiments, since the initial batch may be small relative to the size of the test data (e.g., 20 samples or less), it is likely that the first training attempts will be insufficient completely train the online classification system in the first training attempt. However, each iteration will improve the learning results.
It will be understood that each block of the flowchart the illustrations, and combinations of blocks in the flowchart illustrations, can be implemented by computer program instructions.
