Hybrid LLMs suffer from "Competing Learning"; staged training offers solution

Researchers have identified a phenomenon called "Competing Learning" in hybrid language models, where recurrence and attention layers interfere with each other's learning processes. They found that recurrence layers often learn retrieval functions faster, suppressing attention's ability to do so. To address this, a staged training procedure was proposed, which involves stopping weight updates in recurrence layers during training. This method demonstrated significant improvements in language modeling, common-sense reasoning, and retrieval tasks for models up to 1 billion parameters. AI

IMPACT This research could lead to more efficient and effective training methods for future hybrid language models.
