+# FBCNet
+
+FBCNet from Mane, R et al (2021) .
+
+> **Architecture-only repository.** This repo documents the
+> `braindecode.models.FBCNet` class. **No pretrained weights are
+> distributed here** — instantiate the model and train it on your own
+> data, or fine-tune from a published foundation-model checkpoint
+> separately.
+
+## Quick start
+
+```bash
+pip install braindecode
+```
+
+```python
+from braindecode.models import FBCNet
+
+model = FBCNet(
+    n_chans=22,
+    sfreq=250,
+    input_window_seconds=4.0,
+    n_outputs=4,
+)
+```
+
+The signal-shape arguments above are example defaults — adjust them
+to match your recording.

+
+ The FBCNet model applies spatial convolution and variance calculation along
+ the time axis, inspired by the Filter Bank Common Spatial Pattern (FBCSP)
+ algorithm.
+
+ Notes
+ -----
+ This implementation is not guaranteed to be correct and has not been checked
+ by the original authors; it has only been reimplemented from the paper
+ description and source code [fbcnetcode2021]_. There is a difference in the
+ activation function; in the paper, the ELU is used as the activation function,
+ but in the original code, SiLU is used. We followed the code.
+
+ Parameters
+ ----------
+ n_bands : int or None or list[tuple[int, int]]], default=9
+     Number of frequency bands. Could
+ n_filters_spat : int, default=32
+     Number of spatial filters for the first convolution.
+ n_dim: int, default=3
+     Number of dimensions for the temporal reductor
+ temporal_layer : str, default='LogVarLayer'
+     Type of temporal aggregator layer. Options: 'VarLayer', 'StdLayer',
+     'LogVarLayer', 'MeanLayer', 'MaxLayer'.
+ stride_factor : int, default=4
+     Stride factor for reshaping.
+ activation : nn.Module, default=nn.SiLU
+     Activation function class to apply in Spatial Convolution Block.
+ cnn_max_norm : float, default=2.0
+     Maximum norm for the spatial convolution layer.
+ linear_max_norm : float, default=0.5
+     Maximum norm for the final linear layer.
+ filter_parameters: dict, default None
+     Dictionary of parameters to use for the FilterBankLayer.
+     If None, a default Chebyshev Type II filter with transition bandwidth of
+     2 Hz and stop-band ripple of 30 dB will be used.

+ .. rubric:: Hugging Face Hub integration
+
+ When the optional ``huggingface_hub`` package is installed, all models
+ automatically gain the ability to be pushed to and loaded from the
+ Hugging Face Hub. Install with::
+
+     pip install braindecode[hub]
+
+ **Pushing a model to the Hub:**
+
+ .. code::
+     from braindecode.models import FBCNet
+
+     # Train your model
+     model = FBCNet(n_chans=22, n_outputs=4, n_times=1000)
+     # ... training code ...
+
+     # Push to the Hub
+     model.push_to_hub(
+         repo_id="username/my-fbcnet-model",
+         commit_message="Initial model upload",
+     )
+
+ **Loading a model from the Hub:**
+
+ .. code::
+     from braindecode.models import FBCNet
+
+     # Load pretrained model
+     model = FBCNet.from_pretrained("username/my-fbcnet-model")
+
+     # Load with a different number of outputs (head is rebuilt automatically)
+     model = FBCNet.from_pretrained("username/my-fbcnet-model", n_outputs=4)
+
+ **Extracting features and replacing the head:**
+
+ .. code::
+     import torch
+
+     x = torch.randn(1, model.n_chans, model.n_times)
+     # Extract encoder features (consistent dict across all models)
+     out = model(x, return_features=True)
+     features = out["features"]
+
+     # Replace the classification head
+     model.reset_head(n_outputs=10)
+
+ **Saving and restoring full configuration:**
+
+ .. code::
+     import json
+
+     config = model.get_config()            # all __init__ params
+     with open("config.json", "w") as f:
+         json.dump(config, f)
+
+     model2 = FBCNet.from_config(config)    # reconstruct (no weights)
+
+ All model parameters (both EEG-specific and model-specific such as
+ dropout rates, activation functions, number of filters) are automatically
+ saved to the Hub and restored when loading.
+
