Hi Krish, Nice Video and well explained. Although I would like to point out on the FNR which is FN/P=FN/(FN+TP). Confusion matrix is always confusing. Love your work and I have started following you.

Hello @Krish, in this lecture you wrote wrong formula for FPR and FNR. FPR = FP / N = FP / (FP + TN); FNR = FN /(FN + TP). But you did correct in your Data Science Interview Question Playlist. Please let me know if I'm right.

You wrote TP FP TN FN inside the Confusion Matrix cells in the case of binary classification. But, how are we going to right such notation in case of multi-class classification ?

Krish u explain in an awesome way but Formula for FPR and FNR is wrong ! Formula for FPR is (FP/N) i.e. FPR=FP/(TN+FP) and formula for FNR is (FN/P) i.e. FNR = FN/(TP+FN)
@pradeepvn86274 жыл бұрын
If 900 results are Correct means it can be True Positive or True Negative. Similarly if 100 results are wrong, it can False Positive or False Negative. Please correct me if my understanding is wrong.
