I am curious as to what kind of feature processing I can do (and to similar other features) which makes it amenable for kNN.
Here's what I tried:
In an attempt to convert the feature from exponential (here) to normal distribution, I did the ecdf = exponential.CDF(X) and then normal.inverseCDF(ecdf). But the resulting distribution is also exponential in nature.
In terms of feature pre-processing, what else can I do?
