This paper addresses the challenge of adapting time series data to a new domain without labor-intensive label annotations. Unsupervised and Semi-supervised Domain Adaptation (UDA and SSDA) have been effective in utilizing pre-labeled source data for training on unlabeled or partially labeled target data, but existing methods compromise performance when directly adapting labeled source samples with unlabelled target samples. The authors investigate the limitations of these methods and explore alternative approaches to ensure domain adaptation without sacrificing the performance of downstream classification tasks.

This paper is about making it easier to use time series data in new situations without having to label all the data by hand. Right now, we can do this with images and words, but not with time series data. Some methods have been developed to help with this problem, like using pre-labeled data to train on unlabeled or partially labeled new data. But these methods can actually make things worse if they’re not careful. The authors are trying to figure out why this is happening and how we can do better.
