1. Background knowledge In just the end of the cat Big Data S1 competition, logic regression is common use and the effect of a good algorithm. (1) return Let's say what is regression, for example, we have two types of data, each with 500 points, when we draw these points, there will be a line between the two sets of data, we draw this curve (because it is very likely non-linear), is regression. We use a lot of data to find this line, and to fit the

These days, take over a colleague's code, about the development of micro-letter interface, that a heap of if, see Brother egg pain, this problem is also a lot of beginners easy to make, so specially to write this refactoring.

Of course, if there are only one or two, or 3, this is not a very good

In principle, a computer is a very simple thing. It is a logic processor. All the work done by a computer is finally converted into logical operations. Therefore, anything that can perform basic logical operations (non, and, and) can be used to form a computer. The idea of computer was proposed as early as the 17th century, but it can only be mechanically used. The first computer in the modern sense is implemented by electronic tubes, but its applicat
