comment How to obtain the class conditional probability when using KNN classifier?
Should we learn the coefficients $B_0$ and $B_1$ ?!

comment How to obtain the class conditional probability when using KNN classifier?
Using that kind of smoothing, we will just get a the same probability values for all classes having $N_i = 0$, so instead of having $P(y_i|x) = 0$, we will get $P(y_i|x) = \frac{s}{K + C \times s} = constant$. Does that change something compared to the 0 probabilities case ?

What do you mean by "using the class probability in the whole data" ? Can you please give more details (by editing your current answer) ? Thanks.
