Hi Ighoyota ben
Providing a class label for Machine learning is fully depends on you. For
binary classification generally, labels are 0 and 1.
For your task, classification of low-risk and high-risk class labels
assignment based on your work (what you want to predict). For example, if
your work is finding high-risk EEG, then the high-risk class is a positive
class. Assing '1' for the class label for high-risk related features.



Low-risk (take as 0)

high-risk (take as 1)
for more clarification about positive class and negative class

> Do i have to choose one feature as my label

> For example
> I have collected EEG data during two condition experiment (decision making
> under low risk and decision making under high-risk condition)
> My labels here are high and low risk
> How do I represent this during my model development
> Also, can someone point me to how to some feature selection examples,
