Labeling Experience

AI Data Labeling Specialist

TolokaImageClassification

As an AI Data Labeling Specialist at Toloka AI, I contributed to computer vision and NLP machine learning pipelines by annotating and labeling large volumes of images, audio, and text data. I consistently maintained high accuracy standards and improved model training data quality through detailed multi-class image classification, object detection, semantic segmentation, and text-based tasks. My responsibilities included validating annotations, collaborating on RLHF projects, and resolving edge case ambiguities. • Annotated and labeled over 10,000 images, audio, and text samples monthly for datasets. • Performed image classification, object detection with bounding boxes, and segmentation. • Contributed to sentiment analysis, text classification, and RLHF response ranking tasks. • Utilized Toloka's proprietary platform tools for labeling and QA processes.
