In case of 2 classes, the threshold is 0.5: if P (Y=0) > 0.5 then obviously P (Y=0) > P (Y=1). The same stands for the multiclass setting: again, it chooses the class with the biggest probability (see e.g. Ng's lectures, the bottom lines). trabant 601 toyWebb27 dec. 2024 · Thus the output of logistic regression always lies between 0 and 1.
