1. ## Help! Simplification of Kullback Liebler Divergence

1
I have been given this question and I need to simplify it using laplacian approximation but am unsure of how to answer it any help is greatly appreciated:

Kullback Liebler Divergence

D (q || p) = ∑i qi log qi/pi.

To measure the divergence of the probability distribution q (the 1 minute window) from a reference distribution p.

where qi = ri/n and Pi=ri/n

Where the ith value is observed ri times out of n during the 1 minute window.
