Classification: CPC G | IPC G

Claim 10:
11. A neural network apparatus that performs a class incremental learning, the neural network apparatus comprising:
a processor configured to:
train an autoencoder using first input embeddings with respect to a first class group,
calculate a contribution value of each of parameters of the autoencoder and a first plurality of representative values with respect to each of at least one first class included in the first class group in the training of the autoencoder,
retrain an autoencoder using second input embeddings with respect to a second class group, and
update the contribution value of the each of the parameters, for the retraining, and to calculate a second plurality of representative values with respect to each of at least one second class included in the second class group in retraining the autoencoder using at least one first class of the first class group.
