Classifier learning system and classifier generation system including the same

A classifier generation system comprising:

• a data collector configured to collect training data having a feature space including a plurality of features from each of a plurality of environments;
• and
• a classifier learning system configured to train a classifier based on the training data, and
• wherein the classifier learning system includes:
• a classifier configured to train the training data based on a classification algorithm;
• a feature weight generation module configured to generate a feature weight based on an artificial neural network and an amount of mutual information between the plurality of features of the training data;
• and
• a data sampling module configured to generate sampling data by performing a feature space restoration operation based on the training data and a previous feature space of previous data on which the training is completed in the classifier, and
• wherein the classifier is configured to train the sampling data, and
• wherein the classifier includes a plurality of feature-specific classifiers to which the feature weights corresponding to each of the plurality of features are assigned.
