Doubt in video concept

#1

at 5:17 in the video we made a labels matrix and then we wrote labels[prob>0.5] = 1, but we just initialized the labels array above this step with all 0’s , the how will the value be >0.5. Should’nt we have first filled all the prob values in the labels array first and then write labels[prob>0.5]=1. Plz correct me if m wrong…

Hey @saksham_thukral, in case if we have filled the prob value in labels array, and than did labels[prob>0.5]=1, than the values which are <=0.5 will remain unchanged, they will not contain 0 instead a real number between 0 and 0.5.

So instead we first kept all labels as zeros, and finally we get the positions where prob value is greater than 0.5 by prob>0.5 and at that postition we put 1.

Also if you find your doubt is resolved, then mark it as resolved.
