Introduction ☕

“Our intelligence is what makes us human, and A.I. is an extension of that quality.” — Yann LeCun Professor, New York University

Motivation 😇

Are computers smart?

But, then we would have to consider every possible steps and all the minute details! Wouldn’t that be so difficult?

Instead of telling computers the exact details to learn, we now let the programs (computer) to figure out how to solve by itself.

Output(Y) = Weights(W)*Inputs(X) + Biases(B)

Deep Learning 🤖

What exactly is deep learning? What is so special about it?
