Freelancer Overview

I conducted AI data training, including response ranking, error labeling, response editing, and reinforcement learning with human feedback (RLHF). In addition, I helped to develop and fine-tune LLM prompts and assess AI-generated content for factual accuracy and I trained AI conversational models using JSON-based API orchestrations and supervised fine-tuning (SFT).

The project was in service to an enterprise LLM. The goal was to train the LLM to be given a set of instructions to conform to to client's business needs and only provide information and services based on the preamble instructions. Then, test the preamble by crafting prompts to test it. Lastly, we used RLHF methods to label any errors or unwanted behavior.
