## Summary

A new framework called the LLM as Forecasting Planner (LAFP) has been introduced, which combines time-series foundation models (TSFMs) with large language models (LLMs) to improve forecasting capabilities. This innovative approach treats forecasting as a planning problem, allowing for the generation of trajectories by TSFMs while LLMs provide guidance and evaluation. Notably, LAFP eliminates the need for retraining, making it a more efficient solution for time-series forecasting tasks.

## Key takeaways

- The LAFP framework integrates LLMs with time-series models for enhanced forecasting.
- By treating forecasting as a planning problem, LAFP allows for effective trajectory generation.
- The approach is training-free, streamlining the forecasting process.

## Why it matters

This development represents a significant advancement in the field of forecasting, potentially leading to more accurate predictions across various industries that rely on time-series data.

- **Product managers:** For product managers, the LAFP framework could lead to more reliable forecasting tools, enabling better decision-making and resource allocation based on predictive insights.
- **Developers:** Developers and engineers can leverage the LAFP approach to build more efficient forecasting applications without the overhead of retraining models, thus accelerating deployment timelines.
- **Students and job seekers:** Students and job-seekers should note that understanding frameworks like LAFP can enhance their skill set in data science and machine learning, making them more competitive in the job market.

### 作为预测规划者的LLM：无训练文本条件的时间序列基础模型

一种名为LLM作为预测规划者（LAFP）的新框架被引入，它将时间序列基础模型（TSFM）与大型语言模型（LLM）结合，以提高预测能力。这种创新的方法将预测视为规划问题，使得TSFM能够生成轨迹，而LLM提供指导和评估。值得注意的是，LAFP消除了重新训练的需求，使其成为时间序列预测任务的更高效解决方案。

**要点：**

- LAFP框架将LLM与时间序列模型集成，以增强预测能力。
- 通过将预测视为规划问题，LAFP实现了有效的轨迹生成。
- 该方法无需训练，简化了预测过程。

**为什么重要：** 这一发展代表了预测领域的重大进步，可能导致依赖时间序列数据的各个行业更准确的预测。
