报告摘要:
The scarcity of labeled data is one of the main challenges of applying deep learning models on time series data in the real world. Therefore, several approaches, e.g., transfer learning, self-supervised learning, and semi-supervised learning, have been recently developed to promote the capability of deep learning models from the limited time series labels. In this talk, we will briefly review the existing approaches that address the scarcity of labeled data problem in time series data, and categorize them as in-domain solutions and cross-domain solutions. Then, we will share our own capabilities in this topic. We first introduce two self-supervised learning methods called TS-TCC and CA-TCC for in-domain time series representation learning. We also present our method called SEA and our benchmarking suite called AdaTime as cross-domain solutions. Lastly, we discuss the limitations of these methods and provide future directions in this field.
