Quickstart

pip install moabb

import moabb
from moabb.datasets import BNCI2014_001
from moabb.evaluations import CrossSessionEvaluation
from moabb.paradigms import LeftRightImagery
from moabb.pipelines.features import LogVariance

from sklearn.discriminant_analysis import LinearDiscriminantAnalysis as LDA
from sklearn.pipeline import make_pipeline

moabb.set_log_level("info")

pipelines = {"LogVar+LDA": make_pipeline(LogVariance(), LDA())}

dataset = BNCI2014_001()
dataset.subject_list = dataset.subject_list[:2]

paradigm = LeftRightImagery(fmin=8, fmax=35)
evaluation = CrossSessionEvaluation(paradigm=paradigm, datasets=[dataset])
results = evaluation.process(pipelines)

print(results.head())

Disclaimer

This is an open science project that may evolve depending on the need of the community.

The problem

Brain-Computer Interfaces allow to interact with a computer using brain signals. In this project, we focus mostly on electroencephalographic signals (EEG), that is a very active research domain, with worldwide scientific contributions. Still:

• Reproducible Research in BCI has a long way to go.
• While many BCI datasets are made freely available, researchers do not publish code, and reproducing results required to benchmark new algorithms turns out to be trickier than it should be.
• Performances can be significantly impacted by parameters of the preprocessing steps, toolboxes used and implementation “tricks” that are almost never reported in the literature.

As a result, there is no comprehensive benchmark of BCI algorithms, and newcomers are spending a tremendous amount of time browsing literature to find out what algorithm works best and on which dataset.

The solution

The Mother of all BCI Benchmarks allows to:

• Build a comprehensive benchmark of popular BCI algorithms applied on an extensive list of freely available EEG datasets.
• The code is available on GitHub, serving as a reference point for the future algorithmic developments.
• Algorithms can be ranked and promoted on a website, providing a clear picture of the different solutions available in the field.

This project will be successful when we read in an abstract “ … the proposed method obtained a score of 89% on the MOABB (Mother of All BCI Benchmarks), outperforming the state of the art by 5% ...”.

Core Team
