Learning Probabilistic Embeddings for Unsupervised Action Segmentation
Shuai Li, Duc Manh Vu, Juergen Gall
This paper concerns the problem of unsupervised temporal action segmentation for long, untrimmed videos. Recent successful approaches follow a joint representation learning and clustering paradigm, where optimal transport (OT) is adopted to produce pseudo labels for learning fram…
