Hi Sumit, I follow all your sessions and I tried to standaize for Iris dataset and it is giving mean = - 4.7 and standard divination = 1.0

I feel like we will compromise the information about relation between two points as the shape of the pdf will change while in normalization relative distance between points remains unaffected(correct me if i'm wrong).
