Data Annotator (Outlier AI)

OtherText
As a Data Annotator, I trained and evaluated large language models by conducting structured data annotation and response ranking focused on mathematical and physical reasoning. I produced high-quality reference solutions, systematically identified logical and factual errors, and applied rigorous evaluation criteria to enhance model accuracy and consistency. My work directly contributed to improving the problem-solving performance of state-of-the-art AI systems. • Conducted detailed assessment and feedback for AI-generated responses. • Ensured precise annotation standards using best practices. • Collaborated remotely to deliver time-sensitive evaluation projects. • Consistently reviewed and refined evaluation processes to achieve optimal model outcomes.
