+# SPARCNet
+
+Seizures, Periodic and Rhythmic pattern Continuum Neural Network (SPaRCNet) from Jing et al (2023) .
+
+> **Architecture-only repository.** This repo documents the
+> `braindecode.models.SPARCNet` 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 SPARCNet
+
+model = SPARCNet(
+    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.

+
+
+
+ This is a temporal CNN model for biosignal classification based on the DenseNet
+ architecture.
+
+ The model is based on the unofficial implementation [Code2023]_.
+
+ .. versionadded:: 0.9
+
+ Notes
+ -----
+ This implementation is not guaranteed to be correct, has not been checked
+ by original authors.
+
+ Parameters
+ ----------
+ block_layers : int, optional
+     Number of layers per dense block. Default is 4.
+ growth_rate : int, optional
+     Growth rate of the DenseNet. Default is 16.
+ bn_size : int, optional
+     Bottleneck size. Default is 16.
+ drop_prob : float, optional
+     Dropout rate. Default is 0.5.
+ conv_bias : bool, optional
+     Whether to use bias in convolutional layers. Default is True.
+ batch_norm : bool, optional
+     Whether to use batch normalization. Default is True.
+ activation: nn.Module, default=nn.ELU
+     Activation function class to apply. Should be a PyTorch activation
+     module class like ``nn.ReLU`` or ``nn.ELU``. Default is ``nn.ELU``.

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