Labeling Experience

AI Trainer & Data Annotator

AppenTextRLHF

As an AI Trainer and Data Annotator at Open Train AI, I annotated and labeled datasets across text, images, and audio for supervised machine learning pipelines. The role included providing Reinforcement Learning from Human Feedback (RLHF) by evaluating and ranking AI outputs, as well as prompt engineering and content moderation. I performed entity recognition, sentiment tagging, and intent classification for NLP datasets, ensuring high-quality annotations met project benchmarks. • Labeled text, image, and audio data for supervised and RLHF applications. • Evaluated AI model outputs for accuracy, relevance, and safety. • Conducted annotation tasks such as entity recognition and sentiment classification. • Performed content moderation and collaborated with remote teams.
