+) this post is based on the lecture and content in the coursera(https://www.coursera.org/) machine learning class (professor)+) you can make new algorithm using original gradient descent function so you can find this functions are sameFeature ScalingWe can speed up gradient descent by having each of our input values in roughly the same range.−1 ≤ x(i) ≤ 1or−0.5 ≤ x(i) ≤ 0.5These aren't exact re..
