Abstract
A continual learning method, comprising: obtaining, for each of a plurality of classes, a mean of each of a plurality of features generated by passing a plurality of training samples to a pre-trained convolutional neural network, and a covariance matrix of the plurality of features, wherein each of the training samples belongs to one of the classes; obtaining extracted features from the pre-trained convolutional neural network for an additional training sample belonging to a class of said classes; generating a centred feature vector using the mean for the class and the extracted features; updating, using the centred feature vector and the covariance matrix, the covariance matrix, wherein said updating is performed for diagonal elements of the covariance matrix but not for off-diagonal elements; updating the mean for the class using the extracted features; and outputting, based on the updated mean and updated covariance matrix, weights of a streaming linear discriminant analysis (SLDA) model.
