Labeling Experience

AI Dataset Annotation Project (Text & Image)

CVATImageClassification

During the AI Dataset Annotation Project, I categorized images for computer vision model development. I ensured tags were consistently applied across large datasets. I contributed directly to building datasets for model training. • Labeled and classified image data for computer vision. • Maintained data integrity and consistency in tags. • Analyzed images for quality and correct categorization. • Worked with annotation tools to increase efficiency.
