RLHF

Freelancer Overview

Experience training Large Language Models (LLMs) on natural language and code generation with a strong foundation in Reinforcement Learning from Human Feedback (RLHF). I've been on diverse projects from SxS comparisons, tool calls evaluations, fact checking, to data analysis, translation and rubrics, ensuring high quality, optimal performance and truthfulness in AI interactions. With a critical eye and comprehensive data analysis capabilities, I have also helped AI models improve their visual reasoning.
