Neuroimaging experiments, especially EEG experiments, need to be cautious of avoiding confounds. A recent TPAMI paper utilizes data that has been reported to have a serious confound issue before. It is demonstrated that their new model and analysis methods do not solve this confound issue, resulting in their claims of high accuracy and neuroscience relevance being invalid.
Neuroimaging experiments in general, and EEG experiments in particular, must take care to avoid confounds. A recent TPAMI paper uses data that suffers from a serious previously reported confound. We demonstrate that their new model and analysis methods do not remedy this confound, and therefore that their claims of high accuracy and neuroscience relevance are invalid.
