Outline

This paper proposes the PromptTSS framework to address the multi-resolution state segmentation and integration challenges of multivariate time-series data collected in diverse fields, including manufacturing and wearable technology. To overcome the limitations of existing methods, which lack multi-resolution processing and adaptability to dynamic environments, we present an integrated model that utilizes a prompt mechanism to capture both coarse and fine patterns through label and boundary information, and dynamically adapts to unknown patterns. Experimental results demonstrate a multi-resolution segmentation accuracy of 24.49%, a single-resolution segmentation accuracy of 17.88%, and up to 599.24% improvement in transfer learning, demonstrating its adaptability to hierarchical states and evolving time-series dynamics. The source code is available on GitHub.
