There is no systematic study of mathematical optimization, but these tools and techniques are commonly used in machine learning, and the most common optimization in machine learning is convex optimization, which can refer to Ng's teaching materials:

Matrix multiplicationA B multiplies the number of columns of a to be equal to the number of rows of B is defined, the result is a row B of the Matrix C, the value ofeach element of C is a corresponding row and b corresponding to the element of the

Use python to generate a verification code ImageIntroduction Basically, you will encounter verification codes when using each network service. It is generally a verification method set by a website to prevent malicious registration and posting. The

Geometric Transformation Geometric transformation can be seen as a change in the space position of an object (or pixel) in an image, or the movement of pixels. Geometric operations require two steps: spatial transformation and gray-level difference.

Introduction to affine transformationsThe affine transformation originates from the Coregraphics framework, and the main function is to draw 2D levels of layers, and almost all the interface elements on the screen of an iOS device are drawn by

As we all know, STL is very convenient to use, in which the imitation function (functor) plays a very important role. It is very important to use the imitation function flexibly to play the powerful function of STL. This article describes in detail
