RTS-LLM: Reconstructing the Intrinsic Temporal Structure of Time Series Using Large Language Models

RTS-LLM is a desktop time series prediction tool designed for non-technical users. Its core lies in using pre-trained large language models (LLMs) to restore the intrinsic temporal structure of data, solving the problem where traditional AI overlooks the natural flow of time. Key product features include: offline-first (localized data to protect privacy), one-click installation, three-step prediction process, support for scenarios like weather/electricity/finance, and being completely free and open source.

Time series prediction is widely applied in fields such as weather forecasting and electricity consumption, but traditional machine learning methods often ignore the intrinsic structure of time (e.g., seasonality, periodicity). RTS-LLM's approach is to transfer the sequence dependency understanding capability of pre-trained LLMs to time series tasks, using their general sequence intuition to resolve this problem.

1. Rediscovery of Temporal Structure: Through architectural design, enable LLMs to identify seasonality, periodicity, trendiness, and the impact of sudden events;
2. Pre-trained Transfer Learning: Utilize LLMs' sequence dependency understanding, in-context learning ability, and multi-scale feature extraction (short-term fluctuations + long-term trends) without needing to train a dedicated model from scratch.

Product Form: Windows desktop application. System requirements: Win10/11, CPU above i5/Ryzen5, 8GB RAM, 5GB storage, independent GPU acceleration. One-click installation (download .exe → follow wizard → desktop shortcut). Usage Process:

1. Prepare CSV data (date/timestamp + value columns);
2. Load pre-trained engine (Weather/Electricity/Finance/General);
3. Import CSV → select prediction steps → export results.

Privacy Protection: All calculations are performed locally, no network required, data never leaves the device—suitable for sensitive data scenarios. Open Source and Free: No subscription fees, friendly to individual researchers and small businesses.

Best Scenarios: Obvious periodicity (seasonal sales), trend changes (user growth), quick prediction needs without a dedicated data team. Limitations: Only applicable to time series prediction, not for static datasets (image/text classification).

RTS-LLM embodies the democratization of AI tools: it does not pursue cutting-edge architectures but focuses on making technology accessible. Success factors:

• Clear positioning for non-technical users;
• Offline-first design to address privacy concerns;
• Pre-trained transfer to reduce costs;
• One-stop encapsulation (from data preparation to result export). It provides a productization example for the promotion of AI technology.
