+# SleepStagerChambon2018
+
+Sleep staging architecture from Chambon et al. (2018) .
+
+> **Architecture-only repository.** This repo documents the
+> `braindecode.models.SleepStagerChambon2018` 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 SleepStagerChambon2018
+
+model = SleepStagerChambon2018(
+    n_chans=2,
+    sfreq=100,
+    input_window_seconds=30.0,
+    n_outputs=5,
+)
+```
+
+The signal-shape arguments above are example defaults — adjust them
+to match your recording.

+     :alt: SleepStagerChambon2018 Architecture
+
+ Convolutional neural network for sleep staging described in [Chambon2018]_.
+
+ Parameters
+ ----------
+ n_conv_chs : int
+     Number of convolutional channels. Set to 8 in [Chambon2018]_.
+ time_conv_size_s : float
+     Size of filters in temporal convolution layers, in seconds. Set to 0.5
+     in [Chambon2018]_ (64 samples at sfreq=128).
+ max_pool_size_s : float
+     Max pooling size, in seconds. Set to 0.125 in [Chambon2018]_ (16
+     samples at sfreq=128).
+ pad_size_s : float
+     Padding size, in seconds. Set to 0.25 in [Chambon2018]_ (half the
+     temporal convolution kernel size).
+ drop_prob : float
+     Dropout rate before the output dense layer.
+ apply_batch_norm : bool
+     If True, apply batch normalization after both temporal convolutional
+     layers.
+ return_feats : bool
+     If True, return the features, i.e. the output of the feature extractor
+     (before the final linear layer). If False, pass the features through
+     the final linear layer.
+ n_channels : int
+     Alias for `n_chans`.
+ input_size_s:
+     Alias for `input_window_seconds`.
+ n_classes:
+     Alias for `n_outputs`.
+ 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``.

+
+ .. 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 SleepStagerChambon2018
+
+     # Train your model
+     model = SleepStagerChambon2018(n_chans=22, n_outputs=4, n_times=1000)
+     # ... training code ...
+
+     # Push to the Hub
+     model.push_to_hub(
+         repo_id="username/my-sleepstagerchambon2018-model",
+         commit_message="Initial model upload",
+     )
+
+ **Loading a model from the Hub:**
+
+ .. code::
+     from braindecode.models import SleepStagerChambon2018
+
+     # Load pretrained model
+     model = SleepStagerChambon2018.from_pretrained("username/my-sleepstagerchambon2018-model")
+
+     # Load with a different number of outputs (head is rebuilt automatically)
+     model = SleepStagerChambon2018.from_pretrained("username/my-sleepstagerchambon2018-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 = SleepStagerChambon2018.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.
+
+ See :ref:`load-pretrained-models` for a complete tutorial.</main>
