Learning Transfers: Kan Extensions for Neural Invariants
Researchers have introduced a categorical framework for understanding transfer learning, defining a universal transferred invariant called Kan extensions. This approach quanties how structure from source tasks can be preserved in target tasks, moving beyond simple accuracy metrics. The framework allows for precise evaluation of transfer discrepancies, even when representations collapse in ways that maintain classification performance but distort topological information. AI
