# InterpolatedSignalJEPA
Channel-interpolating wrapper around :class:`SignalJEPA`.
> **Architecture-only repository.** Documents the
> `braindecode.models.InterpolatedSignalJEPA` class. **No pretrained weights are
> distributed here.** Instantiate the model and train it on your own
> data.
## Quick start
```bash
pip install braindecode
```
```python
from braindecode.models import InterpolatedSignalJEPA
model = InterpolatedSignalJEPA(
n_chans=22,
sfreq=250,
input_window_seconds=4.0,
n_outputs=4,
)
```
The signal-shape arguments above are illustrative defaults — adjust to
match your recording.
