A new paper explores the impact of abstract pretraining on language models, demonstrating that even a small amount of abstract data can significantly improve reasoning capabilities without affecting perplexity. The study found that a warm-up using a stack-manipulation task, which requires compositional and state-tracking skills, led to notable gains in multi-hop question answering on datasets like MUSIQUE, HOTPOTQA, and 2WIKIMULTIHOPQA. The research indicates that the structure and timing of this abstract training are crucial for its effectiveness, with benefits persisting through subsequent natural language pretraining. AI
IMPACT This research suggests a new method for improving LLM reasoning capabilities by incorporating abstract training tasks, potentially leading to more capable models for complex question-answering scenarios.
