Catastrophic Forgetting

When a neural network trained on new data suddenly loses its ability to perform well on previously learned tasks.

Definition

When a neural network trained on new data suddenly loses its ability to perform well on previously learned tasks. It's a major challenge for continual learning — the model overwrites old knowledge with new patterns. Various techniques like elastic weight consolidation try to mitigate this.
