ChatTS-14B Model

ChatTS focuses on Understanding and Reasoning about time series, much like what vision/video/audio-MLLMs do. This repo provides code, datasets and model for ChatTS: ChatTS: Aligning Time Series with LLMs via Synthetic Data for Enhanced Understanding and Reasoning.

Here is an example of a ChatTS application, which allows users to interact with a LLM to understand and reason about time series data:

Usage

This model is fine-tuned on the QWen2.5-14B-Instruct (https://huggingface.co./Qwen/Qwen2.5-14B-Instruct) model. For more usage details, please refer to the README.md in the ChatTS repository.
