Benchmarking on MOABB with Braindecode (PyTorch) deep net architectures#
This example shows how to use MOABB to benchmark a set of Braindecode pipelines (deep learning architectures) on all available datasets. For this example, we will use only 2 datasets to keep the computation time low, but this benchmark is designed to easily scale to many datasets.

In this example, we will use only 2 subjects from the dataset BNCI2014_001 and BNCI2014_004.
Running the benchmark#
The benchmark is run using the benchmark function. You need to specify the
folder containing the pipelines, the kind of evaluation, and the paradigm
to use. By default, the benchmark will use all available datasets for all
paradigms listed in the pipelines. You could restrict to specific evaluation and
paradigm using the evaluations and paradigms arguments.
To save computation time, the results are cached. If you want to re-run the
benchmark, you can set the overwrite argument to True.
It is possible to indicate the folder to cache the results and the one to save
the analysis & figures. By default, the results are saved in the results
folder, and the analysis & figures are saved in the benchmark folder.
This code is implemented to run on CPU. If you’re using a GPU, do not use multithreading (i.e. set n_jobs=1)
In order to allow the benchmark function to work with return_epoch=True (Required to use Braindecode( we need to call each pipeline as “braindecode_xxx…”, with xxx the name of the model to be handled correctly by the benchmark function.
