How to create a binary svm classifier?
Afficher commentaires plus anciens
I have 5 sets of data each with 3 runs of eeg signal acquisitions, and I'm to create a classifier that will distinguish between the rest and mental activity in each run. So first ten seconds are mental activity and then rest for 20s. The class labels are given but its just [1 2 1 2 1 2 1 2 1 2 1 2] for class 1 being mental activity and 2 being rest, for all runs and subjects? To use fitcsvm I need the Y labels array but am not sure how to get that

The Y labels vector is the same as the class labels vector.

Do any of those operations change the column's identification as belonging to mental activity or rest?

As long as you keep columns separate you will be fine. (Each column is an individual sample.)

Did you try the Classification Learner app, on the Apps tab, and have the wizard export the code for you?
