# DynaMix: Zero-shot Forecasting of Dynamical Systems
This DynaMix demo is an interactive Gradio app for zero-shot dynamical systems reconstruction using the DynaMix architecture (accepted NeurIPS 2025 paper [](https://arxiv.org/abs/2505.13192)). It loads pretrained models from the Hugging Face Hub (see [DynaMix model](https://huggingface.co/DurstewitzLab/dynamix)) and provides predictions from uploaded context data.
### Key Features
- **Zero-shot forecasting**: Powered by DynaMix model architecture
- **Custom Context Upload**: Upload your CSV/NPY data or choose a preset (Lorenz63, Noisy Sine, Chua, Selkov)
- **Interactive Settings**: Configure forecast settings
- **Visualizations**: Plots of context data and forecast
- **Exports**: Download forecast as CSV and NPY
## Using the Application
### Data Input
You can either upload your own data or choose a preset dataset from the left panel.
- **Upload**: Accepts `.csv` or `.npy` files
- **Presets**: `Noisy Sine`, `Lorenz63`, `Chua`, `Selkov`
Supported data formats:
- **NPY files**: Numpy array of shape `(time_steps, dimensions)`. 1D time series arrays are auto-expanded to `(time_steps, 1)`; otherwise must be 2D with at least 2 time steps and ≥1 dimension.
- **CSV files**: Each column is a dimension; each row is a time step. Only numeric columns are used. Data must be 2D with at least 2 time steps and ≥1 dimension.
Example CSV format:
```csv
dim_1,dim_2,dim_3
0.1,0.2,0.3
0.4,0.5,0.6
0.7,0.8,0.9
```
### Forecast Settings
- **Model Selection**: Select the pretrained model to use for forecasting.
- **Forecast Length**: Number of future steps to generate (`1`–`2001`, step `100`, default `512`)
- **Advanced Settings**
- **Preprocessing Method**: Method to use for preprocessing the context data (for cases where input dims < model dims)
- **Standardize**: Normalize context to zero mean and unit variance (default: enabled)
- **Fit Nonstationary**: Account for non-stationary trends in the data (default: disabled)
- **Context Steps**: Maximum number of last steps from the uploaded data to use as context. If your uploaded sequence is longer, it will be truncated to the most recent `Context Steps`. (default `2048`)
### Outputs
- **Interactive Plot**: Shows historical context (blue) and forecast (red) per dimension, up to 15 dimensions.
- **Files**:
- `forecast.csv`: Full forecast for all dimensions.
- `forecast.npy`: Full forecast ndarray including all dimensions.
