# BDTCN
Braindecode TCN from Gemein, L et al (2020) [gemein2020].
> **Architecture-only repository.** Documents the
> `braindecode.models.BDTCN` 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 BDTCN
model = BDTCN(
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.

## Architecture
## Parameters
| Parameter | Type | Description |
|---|---|---|
| `n_filters: int` | — | number of output filters of each convolution |
| `n_blocks: int` | — | number of temporal blocks in the network |
| `kernel_size: int` | — | kernel size of the convolutions |
| `drop_prob: float` | — | dropout probability |
| `activation: nn.Module, default=nn.ReLU` | — | Activation function class to apply. Should be a PyTorch activation module class like `nn.ReLU` or `nn.ELU`. Default is `nn.ReLU`. |
