## 1. What’s machine learning

There are several types of learning, Supervised Learning, Unsupervised Learning, Semi-Supervised Learning, Reinforcement learning.

### Derivatives for basic functions are known. For example if f (x) = x 2 , then f 0 (x) = 2x; if f (x) = 2x then f 0 (x) = 2; if f (x) = 2 then f 0 (x) = 0 (the derivative of any function f (x) = c, where c is a constant value, is zero).

Given this, finding local minima in a function would be finding points (x) in the domain for which f’(x) = 0, and for which f’(x+1) > 0 and f’(x-1) > 0.

### Integral is an equivalent of the summation over all values of the function when the function has a continuous domain. It equals the area under the curve of the function.
