Data Labeller (Contract)
As a Data Labeller at Uber AI, I was responsible for annotating data for computer vision and perception models, including 3D LiDAR point cloud processing. My duties included semantic segmentation and categorization of multilingual datasets for intent tagging and sentiment analysis. I also evaluated the relevance of search results and ranking algorithms for user-facing dispatch systems. • Conducted precision labeling and segmentation for autonomous vehicle training datasets. • Supported robust NLP model development through intent and sentiment tagging. • Identified and documented systematic labeling discrepancies for guideline refinement. • Collaborated to boost overall model mean Average Precision (mAP).
