Continual learning using dendritic modulations on view-invariant feedforward weights

The brain is remarkably adept at learning from a continuous stream of data without significantly forgetting previously learnt skills. Conventional machine learning models struggle at continual learning, as weight updates that optimize the current task interfere with previously learnt tasks. A simple remedy to catastrophic forgetting is freezing a network pretrained on a set of base tasks, and training task-specific readouts on this shared trunk. However, this assumes that representations in the frozen network are separable under new tasks, therefore leading to sub-par performance. To continual
