Title: Organizing memories for generalization in complementary learning systems
Abstract: Memorization and generalization are complementary cognitive processes that
jointly promote adaptive behavior. For example, animals should memorize safe routes to
specific water sources and generalize from these memories to discover environmental
features that predict new ones. These functions depend on systems consolidation mechanisms
that construct neocortical memory traces from hippocampal precursors, but why systems
consolidation only applies to a subset of hippocampal memories is unclear. Here we
introduce a new neural network formalization of systems consolidation that reveals an
overlooked tension—unregulated neocortical memory transfer can cause overfitting and harm
generalization in an unpredictable world. We resolve this tension by postulating that
memories only consolidate when it aids generalization. This framework accounts for partial
hippocampal–cortical memory transfer and provides a normative principle for
reconceptualizing numerous observations in the field. Generalization-optimized systems
consolidation thus provides new insight into how adaptive behavior benefits from
complementary learning systems specialized for memorization and generalization.
