P300 Speller training

Post by Ivan Santos »

Hi all,



I wonder if the P300 Speller training scenario can handle an input of several .ov files.



I suppose that training the classifier with one single file (i.e., one single word) is not enough for reaching high classifier performances. Hence, owing to the fact that using a word with a huge number of characters would tire the user, it would be suitable to train the LDA classifier with several files.

If this is not possible, I wonder if the multiple .ov files can be merged somehow in order to “fake” a larger word to train.

Thanks in advance.

Hi, the following thread might be of use,

If you're combining many datasets of the same user on the same day and same cap setup for P300, that could help (in the post its about motor imagery + multiple sessions/users afaik).


Cheers,
Jussi
