Freelance AI Trainer & Data Contributor
As a Freelance AI Trainer & Data Contributor, I evaluated AI-generated responses for factual accuracy and logical consistency. I contributed to the creation and curation of datasets to train and improve large language models. Work involved instruction-following assessment, prompt engineering, and dataset labeling using reputable AI training platforms. • Labeled and evaluated text data on DataAnnotation and Toloka platforms. • Provided bilingual justifications (English and Vietnamese) for AI outputs. • Focused on reinforcement learning from human feedback (RLHF) for LLMs. • Carried out prompt engineering, model quality assessment, and data curation.
