**TL;DR:**

Semi-supervised framework for time series joint alignment and averaging without requiring a regularization hyperparameter (i.e., SoftDTW gamma, DTAN CPA-prior, etc.,)

\*\*Abstract:\*\*In time-series analysis, nonlinear temporal misalignment is a major problem that forestalls even simple averaging. An effective learning-based solution for this problem is the Diffeomorphic Temporal Alignment Net (DTAN), that, by relying on a diffeomorphic temporal transformer net and the amortization of the joint-alignment task, eliminates drawbacks of traditional alignment methods. …
