A primer on motion capture with deep learning: principles, pitfalls, and perspectives
Extracting behavioral measurements non-invasively from video is stymied by the fact that it is
a hard computational problem. Recent advances in deep learning have tremendously …

From local collective behavior to global migratory patterns in white storks
Soaring migrant birds exploit columns of rising air (thermals) to cover large distances with
minimal energy. Using social information while locating thermals may benefit such birds, but …
