Build a comprehensive benchmark of popular Brain-Computer Interface (BCI) algorithms applied on an extensive list of freely available EEG datasets.
This is an open science project that may evolve depending on the need of the community.
First and foremost, Welcome! :tada: Willkommen! :confetti_ball: Bienvenue! :balloon::balloon::balloon:
Thank you for visiting the Mother of all BCI Benchmark repository.
This document is a hub to give you some information about the project. Jump straight to one of the sections below, or just scroll down to find out more.
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:
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 Mother of all BCI Benchmarks allows to:
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% ...”.
To use MOABB, you could simply do:
pip install MOABB
See Troubleshooting section if you have a problem.
You could fork or clone the repository and go to the downloaded directory, then run:
poetry (only once per machine):curl -sSL https://install.python-poetry.org | python3 -poetry config virtualenvs.create falsepoetry installSee contributors' guidelines for detailed explanation.
See pyproject.toml file for full list of dependencies
To ensure it is running correctly, you can also run
python -m unittest moabb.tests
once it is installed.
First, you could take a look at our tutorials that cover the most important concepts and use cases. Also, we have a several examples available.
You might be interested in MOABB documentation
Moabb has a default image to run the benchmark. You have two options to download this image: build from scratch or pull from the docker hub. We recommend pulling from the docker hub.
If this were your first time using docker, you would need to install the docker and login on docker hub. We recommend the official docker documentation for this step, it is essential to follow the instructions.
After installing docker, you can pull the image from the docker hub:
docker pull baristimunha/moabb
# rename the tag to moabb
docker tag baristimunha/moabb moabb
If you want to build the image from scratch, you can use the following command at the root. You may have to login with the API key in the NGC Catalog to run this command.
bash docker/create_docker.sh
With the image downloaded or rebuilt from scratch, you will have an image called moabb.
To run the default benchmark, still at the root of the project, and you can use the
following command:
mkdir dataset
mkdir results
mkdir output
bash docker/run_docker.sh PATH_TO_ROOT_FOLDER
An example of the command is:
cd /home/user/project/moabb
mkdir dataset
mkdir results
mkdir output
bash docker/run_docker.sh /home/user/project/moabb
Note: It is important to use an absolute path for the root folder to run, but you can
modify the run_docker.sh script to save in another path beyond the root of the project. By
default, the script will save the results in the project's root in the folder results,
the datasets in the folder dataset and the output in the folder output.
The list of supported datasets can be found here : https://neurotechx.github.io/moabb/datasets.html
Detailed information regarding datasets (electrodes, trials, sessions) are indicated on the wiki: https://github.com/NeuroTechX/moabb/wiki/Datasets-Support
you can submit a new dataset by mentioning it to this issue. The datasets currently on our radar can be seen here.
The founders of the Mother of all BCI Benchmarks are Alexander Barachant and Vinay Jayaram. This project is under the umbrella of NeuroTechX, the international community for NeuroTech enthusiasts. The project is currently maintained by Sylvain Chevallier.
You! In whatever way you can help.
We need expertise in programming, user experience, software sustainability, documentation and technical writing and project management.
We'd love your feedback along the way.
Our primary goal is to build a comprehensive benchmark of popular BCI algorithms applied on an extensive list of freely available EEG datasets, and we're excited to support the professional development of any and all of our contributors. If you're looking to learn to code, try out working collaboratively, or translate your skills to the digital domain, we're here to help.
If you think you can help in any of the areas listed above (and we bet you can) or in any of the many areas that we haven't yet thought of (and here we're sure you can) then please check out our contributors' guidelines and our roadmap.
Please note that it's very important to us that we maintain a positive and supportive environment for everyone who wants to participate. When you join us we ask that you follow our code of conduct in all interactions both on and offline.
If you want to report a problem or suggest an enhancement, we'd love for you to open an issue at this GitHub repository because then we can get right on it.
For a less formal discussion or exchanging ideas, you can also reach us on the Gitter channel or join our weekly office hours! This an open video meeting happening on a regular basis, please ask the link on the gitter channel. We are also on NeuroTechX Slack #moabb channel.
A dataset handles and abstracts low-level access to the data. The dataset will read data stored locally, in the format in which they have been downloaded, and will convert them into a MNE raw object. There are options to pool all the different recording sessions per subject or to evaluate them separately.
A paradigm defines how the raw data will be converted to trials ready to be processed by a decoding algorithm. This is a function of the paradigm used, i.e. in motor imagery one can have two-class, multi-class, or continuous paradigms; similarly, different preprocessing is necessary for ERP vs ERD paradigms.
An evaluation defines how we go from trials per subject and session to a generalization statistic (AUC score, f-score, accuracy, etc) -- it can be either within-recording-session accuracy, across-session within-subject accuracy, across-subject accuracy, or other transfer learning settings.
Pipeline defines all steps required by an algorithm to obtain predictions. Pipelines are typically a chain of sklearn compatible transformers and end with a sklearn compatible estimator. See Pipelines for more info.
Once an evaluation has been run, the raw results are returned as a DataFrame. This can be further processed via the following commands to generate some basic visualization and statistical comparisons:
from moabb.analysis import analyze
results = evaluation.process(pipeline_dict)
analyze(results)
