Breaking the Reversal Curse in Autoregressive Language Models via Identity Bridge
Researchers demonstrate that the 'reversal curse' — an autoregressive language model's inability to deduce inverse relationships from forward training data — can be mitigated through a simple data regularization technique called Identity Bridge. By adding self-referential training examples (e.g., 'Alice's name is Alice'), a 1B parameter model achieves 50% success on reversal tasks compared to near-zero baseline performance, suggesting LLMs can learn higher-level logical rules rather than merely memorizing facts.
