Piotr Dollár
Technical Staff at Thinking Machines Lab
Dollár helped shape modern computer vision by co-creating COCO, a common benchmark for detecting and describing objects in images. He also developed focal loss, which helps detectors learn from rare examples, and contributed to Segment Anything, a model that can isolate objects without task-specific retraining.
