2020 BCI competition, track 3

The 2020 BCI Competition Track 3 dataset comprises EEG recordings from 15 subjects performing imagined speech tasks involving five distinct commands: 'Hello', 'Help me', 'Stop', 'Thank you', and 'Yes'. Designed for brain-computer interface research, the dataset includes 64-channel EEG recordings sampled at 256 Hz, organized into training, validation, and test sets with annotated trial onsets and durations. The data has been converted to BIDS-compliant EDF format with preserved channel montage information and temporal event markers for each imagined speech trial.
