class braindecode.models.EEGNetv1(n_chans=None, n_outputs=None, n_times=None, final_conv_length='auto', pool_mode='max', second_kernel_size=(2, 32), third_kernel_size=(8, 4), drop_prob=0.25, chs_info=None, input_window_seconds=None, sfreq=None, in_chans=None, n_classes=None, input_window_samples=None, add_log_softmax=True)[source]#

EEGNet model from Lawhern et al. 2016.

See details in [EEGNet].

Parameters:

  • n_chans (int) – Number of EEG channels.

  • n_outputs (int) – Number of outputs of the model. This is the number of classes in the case of classification.

  • n_times (int) – Number of time samples of the input window.

  • final_conv_length – The description is missing.

  • pool_mode – The description is missing.

  • second_kernel_size – The description is missing.

  • third_kernel_size – The description is missing.

  • drop_prob – The description is missing.

  • chs_info (list of dict) – Information about each individual EEG channel. This should be filled with info["chs"]. Refer to mne.Info for more details.

  • input_window_seconds (float) – Length of the input window in seconds.

  • sfreq (float) – Sampling frequency of the EEG recordings.

  • in_chans – Alias for n_chans.

  • n_classes – Alias for n_outputs.

  • input_window_samples – Alias for n_times.

  • add_log_softmax (bool) – Whether to use log-softmax non-linearity as the output function. LogSoftmax final layer will be removed in the future. Please adjust your loss function accordingly (e.g. CrossEntropyLoss)! Check the documentation of the torch.nn loss functions: https://pytorch.org/docs/stable/nn.html#loss-functions.

Raises:

  • ValueError – If some input signal-related parameters are not specified: and can not be inferred.

  • FutureWarning – If add_log_softmax is True, since LogSoftmax final layer: will be removed in the future.

Notes

This implementation is not guaranteed to be correct, has not been checked by original authors, only reimplemented from the paper description.
