This blog requires the basic understanding of Probability and Statistics and Neural Nets. Problem Statement Suppose, we are given the samples from a distribution and distribution is unknown to us. These samples could be anything from images to audio.

A curated list of resources on machine learning, quantum computing, finance etc.

Query Model In Query Model, our task is to compute the function $f(x_1,x_2,….,x_n)$ by accessing $x_i$ through quering the orcale. Oracles can be thought of as a ‘black-box’ by which you can access some information regarding the input, we don’t really care about the internal setup in black-box, it can be easily constructed.
