Introduction in the gradient descent
A bit of theory: Suppose we just need to find a minimum of the one-dimensional function. As early as the 17th century Pierre de Fermat was invented a criterion that allowed solving simple optimization problems, namely, if x* is a minimum point of f*, then: This criterion is based on a linear approximation The closer x to ...
