MiniCTX: Advancing Context-Dependent Theorem Proving in Large Language Models

Understanding Formal Theorem Proving and Its Importance Formal theorem proving is important for assessing the reasoning abilities of large language models (LLMs). It helps automate mathematical tasks. While LLMs can support mathematicians in completing and formalizing proofs, there are challenges in aligning evaluation methods with real-world theorem proving. Challenges in Current Evaluation Methods Current evaluation methods do not accurately reflect the complex nature of mathematical reasoning required for real theorem proving. This raises concerns about how effective LLM-based provers are in practical situations. There is a need for better evaluation frameworks that can truly assess an LLM’s ability to handle complex mathematical proofs. Innovative Approaches to Enhance Theorem-Proving Capabilities Several techniques have been developed to improve the theorem-proving skills of language models: - **Next Tactic Prediction:** Models predict the next step in a proof based on the current situation. - **Premise Retrieval Conditioning:** Relevant mathematical premises are included in the proof generation. - **Informal Proof Conditioning:** Natural language proofs help guide the model’s output. - **File Context Fine-Tuning:** Models can generate complete proofs without needing intermediate steps. While these methods have shown improvements, they often focus on specific aspects rather than the full complexity of theorem proving. Introducing MiniCTX: A New Benchmark System Researchers at Carnegie Mellon University have created MiniCTX, a new benchmark system designed to improve the evaluation of theorem-proving capabilities in LLMs. This system takes a comprehensive approach by including various contextual elements that previous methods missed. Key Features of MiniCTX - **Comprehensive Context Handling:** MiniCTX includes premises, prior proofs, comments, notation, and structural components. - **NTP-TOOLKIT Support:** An automated tool that extracts relevant theorems and contexts from Lean projects, ensuring up-to-date information. - **Robust Dataset:** The system features 376 theorems from various mathematical projects for realistic evaluations. Performance Improvements with Context-Dependent Methods Experiments show significant performance improvements when using context-dependent methods. For example: - A file-tuned model achieved a 35.94% success rate compared to 19.53% for the state-tactic model. - Providing preceding file context to GPT-4o improved its success rate to 27.08% from 11.72%. These results demonstrate the effectiveness of MiniCTX in evaluating context-dependent proving capabilities. Future Directions for Theorem Proving Research suggests several areas for improvement in context-dependent theorem proving: - Effectively handling long contexts without losing important information. - Integrating repository-level context and cross-file dependencies. - Enhancing performance on complex proofs that require extensive reasoning.
