Labeling Experience

Chemical Engineering Subject Matter Expert (SME)

Text

As a Chemical Engineering Subject Matter Expert, I used my technical expertise to evaluate AI-generated responses in STEM fields. My work focused on auditing logic, truthfulness, and accuracy in machine-generated outputs for chemical engineering and analytical chemistry domains. I applied RLHF frameworks and reviewed diverse multimodal data including technical diagrams and text. • Evaluated logic and accuracy of AI responses. • Applied scientific fact-checking to machine outputs. • Validated multimodal technical content and process diagrams. • Audited outputs with an RLHF evaluation system.
