A Multi-Agent System is a computational framework composed of multiple interacting agents that operate autonomously while coordinating to achieve individual or shared objectives. Each agent can perceive its environment, make decisions, and communicate with other agents. These systems are used in artificial intelligence, distributed computing, and robotics to model complex behaviors, enable task decomposition, and support scalable problem solving across domains such as optimization, simulation, and collaborative learning.

Decoding Time Series with LLMs: A Multi-Agent Framework for Cross-Domain Annotation

/in /by

Time series data is ubiquitous across various domains, including manufacturing, finance, and healthcare. High-quality annotations are essential for effectively understanding time series and facilitating downstream tasks. However, obtaining such annotations is challenging, particularly in mission-critical domains. In this paper, we propose TESSA, a multi-agent system designed to automatically generate both general and domain-specific annotations for time series data. TESSA introduces two agents: a general annotation agent and a domain-specific annotation agent. The general agent captures common patterns and knowledge across multiple source domains, leveraging both time-series-wise and text-wise features to generate general annotations. Meanwhile, the domain-specific agent utilizes limited annotations from the target domain to learn domain-specific terminology and generate targeted annotations. Extensive experiments on multiple synthetic and real-world datasets demonstrate that TESSA effectively generates high-quality annotations, outperforming existing methods.
