# VisionTS++: Cross-Modal Time Series Foundation Model with Continual Pre-trained Visual Backbones

This repository hosts the **VisionTS++** model, a state-of-the-art time series foundation model based on continual pre-training of a visual Masked AutoEncoder (MAE) on large-scale time series data. It excels in multivariate and probabilistic time series forecasting by bridging modality gaps between vision and time series data.

The model was introduced in the paper:
[**VisionTS++: Cross-Modal Time Series Foundation Model with Continual Pre-trained Vision Backbones**](https://arxiv.org/abs/2508.04379)

Official GitHub repository: [https://github.com/HALF111/VisionTSpp](https://github.com/HALF111/VisionTSpp)

Experience **VisionTS++** directly in your browser on this [Hugging Face Space](https://huggingface.co/spaces/Lefei/VisionTSpp)! You can upload your own custom time series CSV file for zero-shot forecasting.

## About
VisionTS++ is built upon continual pre-training of a vision model on large-scale time series, addressing key discrepancies in cross-modal transfer from vision to time series. It introduces three key innovations:

1.  **Vision-model-based filtering**: Identifies high-quality sequences to stabilize pre-training and mitigate the data-modality gap.
2.  **Colorized multivariate conversion**: Encodes multivariate series as multi-subfigure RGB images to enhance cross-variate modeling.
3.  **Multi-quantile forecasting**: Uses parallel reconstruction heads to generate quantile forecasts for probabilistic predictions without parametric assumptions.

These innovations allow VisionTS++ to achieve state-of-the-art performance in both in-distribution and out-of-distribution forecasting, demonstrating that vision models can effectively generalize to Time Series Forecasting with appropriate adaptation.


## Installation

The VisionTS++ model is available through the `visionts` package on PyPI.

First, install the package:

```shell
pip install visionts
```

If you want to develop the inference code, you can also build from source:

```shell
git clone https://github.com/HALF111/VisionTSpp.git
cd VisionTSpp
pip install -e .
```

For detailed inference examples and usage with clear visualizations of image reconstruction, please refer to the `demo.ipynb` notebook in the [official GitHub repository](https://github.com/HALF111/VisionTSpp/blob/main/demo.ipynb).
