Formal Logic Deduction

Formal Logic Deduction (FLD) is a project to teach language models deductive reasoning using synthetically generated examples based on formal logic theory.

$\color{red}{(2024/11/21)}$ We are working on the resource release for our NeurIPS 2024 paper, "Enhancing Reasoning Capabilities of LLMs via Principled Synthetic Logic Corpus." The resources will be made available before the conference, i.e., by early December.

[!] News

• We released a Japanese logical benchmark JFLD.

What's good?

FLD serves as ...

• 👊 A Challenging Benchmark for Logical Reasoning: FLD assesses (i) pure reasoning isolated from knowledge, and (ii) diverse reasoning patterns. Indeed, even GPT-4 can solve only about half of the problems.
• 🎓 A Foundation for Learning Logical Reasoning: The FLD corpus teaches the fundamentals of logic, adopting a well-grounded set of atomic deduction rules based on formal logic theory.
• 🚀 A Basis for Future Experimental Studies: It encompasses several toolkits as listed below, paving the way for innovative research.

Contents

• You can use the corpora via 🤗 huggingface hub. See here.
• You can evaluate various LLMs, such as GPT-4 and Llama, by using lm-evlauation-harness or our evaluation scripts.
• You can fine-tune language models on FLD corpora. You can either use a logical-reasoning framework LogiTorch/logitorch, or our training scripts.
• You can generate corpora with your own setting using our corpus generator.
