Summary

V-JEPA is a vision model exclusively trained using a feature prediction objective, learning directly from video data without external supervision. It employs self-supervised learning techniques and prioritizes video feature prediction, achieving significant efficiency gains while maintaining high performance levels. V-JEPA produces versatile visual representations that excel in both motion and appearance-based tasks, showcasing its effectiveness in capturing complex interactions within video data. The model's methodology involves revisiting feature prediction for learning visual representations from video, setting it apart from traditional approaches. V-JEPA demonstrates superior performance across downstream tasks in frozen evaluation, surpassing other models trained with a ViT-L/16 encoder, and utilizing significantly fewer samples during pretraining. Its performance is consistent, particularly excelling in tasks requiring motion understanding, effectively reducing the gap between video and image models on such tasks.
