avalanche.models.PNNLayer

class avalanche.models.PNNLayer(in_features, out_features_per_column, adapter='mlp')[source]

Progressive Neural Network layer.

The adaptation phase assumes that each experience is a separate task. Multiple experiences with the same task label or multiple task labels within the same experience will result in a runtime error.

__init__(in_features, out_features_per_column, adapter='mlp')[source]
Parameters
  • in_features – size of each input sample

  • out_features_per_column – size of each output sample (single column)

  • adapter – adapter type. One of {‘linear’, ‘mlp’} (default=’mlp’)
