CLASS-INCREMENTAL LEARNING OF A CLASSIFIER - A simplified explanation of the abstract

This abstract first appeared for US patent application 18060987 titled 'CLASS-INCREMENTAL LEARNING OF A CLASSIFIER

The present disclosure discusses a method for training a classifier, which involves iteratively receiving training datasets, adding output vectors to memory, retraining the classifier, and updating prototype vectors.

  • The classifier includes a controller and an explicit memory.
  • Training involves receiving multiple training datasets with data samples of novel classes, adding output vectors to memory, retraining the classifier, minimizing distance between output vectors and prototype vectors, updating prototype vectors, and updating the explicit memory.
  • The method aims to improve the classifier's ability to recognize novel classes and adapt to new data.
  • By updating prototype vectors based on new training datasets, the classifier can better generalize and make accurate predictions.
  • This approach enhances the classifier's performance and adaptability in various applications.

Original Abstract Submitted

The present disclosure relates to training a classifier. The classifier includes a controller and an explicit memory. The training may include iteratively receiving one or more second training datasets, each comprising second data samples of a set of one or more associated novel classes, adding to the explicit memory one or more second output vectors indicative of the set of one or more associated novel classes, in response to providing the one or more second training datasets to the classifier, retraining the classifier using the one or more second training datasets and the first training dataset by minimizing a distance between the one or more second output vectors and the one or more prototype vectors, determining a set of updated prototype vectors indicative of first training dataset and the one or more second training datasets, and updating the explicit memory with the set of updated prototype vectors.
