Overview
- New counterfactual optimization method for self-supervised motion learning
- Learns to represent motion by predicting alternative video trajectories
- Outperforms state-of-the-art in video prediction and action recognition
- Identifies meaningful "motion concepts" without human labels
- Shows strong performance on challenging datasets like Something-Something V2
Plain English Explanation
This paper introduces a clever way for AI to understand motion in videos without human guidance. Instead of being told what to look for, the system learns by playing a game of "what if?" with video sequences.
Imagine watching a person throw a ball. Traditional systems might st...
