Lost or Hidden? A Concept-Level Forgetting in Supervised Continual Learning

In three linesDiagnostic study of catastrophic forgetting in continual learning using Sparse Autoencoders. Framework analyzes task-specific information evolution at latent concept level. Finding: most apparent concept-level forgetting is recoverable under linearity assumption; degradation stems from representational accessibility changes rather than complete information erasure.
