To preprocess or not to preprocess your #EEG (when building #ML models) 🔮? 💫We are thrilled to share our latest #preprint, studying the challenge of learning brain-specific biomarkers from EEG 🧠📶 using #ML ⚙️🖥️: https://t.co/1mAgqSzg0o

We compile arguments and evidence from benchmarking age- & sex-prediction on > 2600 EEGs from two large public datasets.

We found that basic artifact rejection consistently led to better model performance, whereas removal of ocular and muscle artifacts hampered performance. As it turns out that those peripheral signals are predictive themselves!

Our results therefore argue in favor of the need to diligently process EEG data, if the goal is to have brain-specific biomarkers (and if prediction is not the only objective).

Our efforts to build more interpretable #ML models for EEG led us to extending the established Morlet wavelet methodology for spectral analysis of EEG to accommodate state-of-the-art ML models based on covariance matrices. This allowed us to perform head-to-head comparisons between classical EEG features and frequency-specific model predictions for, both, brain and artifact signals.

Compared to classical band-pass filtering, wavelets even led to improvements in prediction performance.

Joint work with Philipp Bomatter, @JP4illard, Pilar Garces & Jörg F Hipp.

Thrilled to announce the 0.3 release of hnn-core; a user-friendly python package for the simulation of cortical activity underlying #MEG/#EEG. This update includes a new GUI, and a revamped API to modify/record the network.

`pip install hnn_core[gui]` and give it a try! 🧠🚀

[Mainak Jas @mainakjas]

@DanFeuerriegel Probably a better title would be “EEG data should be sometimes left alone.” The datasets considered were also relatively clean and thus do not require extensive preprocessing. A catch all recommendation for preprocessing is fundamentally flawed

Check out this excellent opportunity to join @MGHMartinos and investigate ASD with #MEG 👇👇👇

@petrzzz @memming I use pyglmnet and it works great! I don't know if it has particular features for building design matrices, but it allows nice control over regularization parameters and different link functions, as well as different scoring functions. @mainakjas

[Mainak Jas @mainakjas]

@DirkGuetlin nice blogpost :) drive by comment ... have you compared to human annotations? decoding accuracy can be high if you have imbalanced distribution of artifacts between the classes ...
