AI Data Annotator & Evaluator - Freelance

OtherText
As an AI Data Annotator & Evaluator, I evaluated and annotated AI-generated outputs across multiple modalities, including text, image, code, and audio/video, to enhance model accuracy. I conducted prompt evaluation and response quality assessments for large language models as part of RLHF workflows. I maintained consistent quality standards and applied structured evaluation rubrics to rate model outputs across diverse high-volume tasks. • Annotated and evaluated text, images, audio, and code outputs from AI systems. • Implemented RLHF (Reinforcement Learning from Human Feedback) for LLMs including prompt and response assessments. • Conducted object detection, segmentation, and scene descriptions for visual data. • Systematically rated outputs using rubrics for accuracy, helpfulness, harmlessness, and coherence.

ImageEvaluation Rating
I performed qualitative evaluations of images produced by an AI model. I conducted side-by-side comparisons of model outputs to determine which image best followed the given prompts, was less AI-Generated, structured rubrics to provide subjective evaluation scores.

TextEntity Ner Classification
I participated in this project to refine the accuracy of entity extraction for an AI model. I performed Named Entity Recognition (NER), conducted qualitative reviews to identify failure modes where the model classified wrongly or missed entities.

TextEvaluation Rating
In this project, I evaluated human-to-human (H2H) datasets to improve the response generation of a conversational AI model. I reviewed multi-turn dialogues and provided evaluation ratings on specific quality rubrics.
