RLHF
As a PhD researcher, I contributed to Reinforcement Learning from Human Feedback (RLHF) processes for AI-driven rehabilitation in a medical setting. My primary role involved evaluating and rating AI feedback and guidance in virtual reality systems that analyze upper limb movement for recovery. I assessed the accuracy and safety of AI outputs, providing critical feedback to refine rehabilitation paths and AI decision-making. • Conducted human-in-the-loop safety and effectiveness reviews. • Annotated patient motion data within VR rehabilitation research. • Ranked and rated AI-generated prompts and recovery plans. • Verified and fact-checked AI-generated physiological outputs.
