VideoSegmentation
I have hands-on experience in AI training and data annotation through projects with Outlier (Aether), where I focused on improving the accuracy, clarity, and reasoning of AI-generated content. My work involved reviewing and labeling text data, ranking and evaluating AI responses, identifying errors, and rewriting outputs to meet strict quality guidelines. I also ensured prompt-response alignment and handled medium to large datasets across diverse topics. I consistently followed annotation standards, conducted self-reviews, and applied feedback from QA teams to maintain high-quality results, strengthening my ability to produce accurate and reliable training data.
