You say 'claim' but then we have clear cases where these techniques work, allowing paralyzed people to control a mouse or play a video game through scalp eeg sensors.
If you quote more than one word, it becomes clear that GP is not disagreeing with you:
> Clueless ML researchers claim to read this and that from brains. [...] ML is great for EEG signal analysis, but you do have to know what you are doing.
1) If you know what you are doing, it's possible to use ML algorithms to control cursor etc. from EEG coming from brain.
2) It's also possible for ML algorithms to enable paralyzed person (neck down) to to control a mouse or play a video game through scalp eeg sensors using eye and muscle artefacts.
Both are good, but the latter is clueless and would work better with better positioning of electrodes. Track eye and muscle tension directly. Paralyzed people care only that it works.
