Abstract
The detection of change points in multivariate signal without access to annotated data is a challenging task. The fully unsupervised approach requires the development of a robust algorithm that can effectively identify unknown a priori patterns. In this article we will present one of the solutions to “Human Activity Segmentation Challenge” ECML/PKDD’23 [4] where the task was to predict the offsets of activity transitions for multivariate time series. The described solution won the first place.
