Section 02

Background: Limitations of Traditional Time-Series Analysis and Opportunities for LLMs

The core challenge of time-series analysis is capturing temporal dependencies. Traditional methods such as ARIMA and LSTM have limitations: heavy feature engineering, limited generalization ability, insufficient interpretability, and difficulty in multimodal fusion. The semantic understanding, reasoning, and knowledge integration capabilities of LLMs provide new ideas for solving these problems.

Methods: Reasoning Capabilities and Technical Architecture of Agent Systems

Reasoning Capabilities

  • Temporal pattern recognition: Identify periodicity, trends, and anomalies and describe them in natural language;
  • Causal reasoning: Infer causal relationships by combining external knowledge bases;
  • Multi-step reasoning: Decompose complex prediction tasks through chain-of-thought.

Agent Systems

  • Tool calling: Call specialized time-series analysis tools to enhance capabilities;
  • Memory management: Track historical analysis results for continuous learning;
  • Multi-agent collaboration: Professional agents collaborate to complete subtasks.
