LLM Alignment: Math Reasoning Dataset (Personal Project)

TextData Collection
I designed a high-difficulty math problem dataset focused on combinatorics and number theory to evaluate LLMs. I created and curated over 500 problems and implemented a quality control workflow to verify solution factuality and mathematical soundness. I systematically flagged and corrected AI-generated content that contained hallucinated or incorrect theorems. • Compiled and structured datasets for LLM benchmarking. • Developed verification flow for math solutions. • Focused on rigor in combinatorics and number theory domains. • Applied judgment to accept or reject AI solutions based on truthfulness.

TextPrompt Response Writing SFT
As a Freelance AI Trainer specializing in mathematics, I curated and generated high-quality prompt-response pairs to train large language models. I conducted RLHF by evaluating model outputs for mathematical accuracy, logical reasoning, and pedagogical soundness. I implemented extensive adversarial testing workflows to uncover weaknesses in AI mathematical reasoning and factual grounding. • Generated and formatted mathematical problems and solutions using LaTeX for precision. • Performed RLHF to rank and select the most pedagogically effective model responses. • Designed adversarial test cases targeting algebra, proofs, and word problems. • Ensured outputs followed strict logical and factual QA procedures.
