## Before that's all

Hey. I am Dima and I do not know the patterns. As for the tester, do not say that it is problematic. How for the automation ? Well, let's be honest, you can also live.

From chat rooms, conferences and communication with colleagues, it is understandable: the main pattern - PageObject - is learned, what else is needed?

## The model of polynomial regression

In simple terms, the regression model in mathematical statistics is built on the basis of known data, in whose role pairs of numbers appear. The number of such pairs is predetermined. If we imagine that the first number in the pair is the value of the coordinate

, and the second -

, then the set of such pairs of numbers can be represented on the plane in a Cartesian coordinate system in the form of a set of points. These pairs of numbers are not taken by chance. In practice, as a rule, the second number depends on the first. To construct a regression means to select a line (more precisely, a function) that approximates (approximates) ...

The project, within the framework of which such a system was developed, was named " RF-Pose ". AI does not just feel that someone is behind the wall, the machine even "sees" what a person is ...
