Machine Learning--Logistic Regression

Logistic Regression Fitting some data points with a straight line awakens. The process of fitting is called regression, and this straight line is called the best fit line. The main idea of using classification is to establish regression formulas to classify boundary lines based on existing data. The term "regression" here derives fr ...

Getting started with Python -- object oriented

Basic overview of object oriented Object oriented programming (OOP): more extensible and readable. Object oriented programming encapsulates data and operation data into objects. The way of organizing code and data is closer to human thinking and improves programming efficiency.python supports many programming paradigms such as object-oriented, ...

Python shallow and deep copies

1. Difference between = = and is ==Operator compares values between objects for equality.The is operator compares whether the identities of objects are equal, that is, whether they are the same object and point to the same memory address. In Python, the identity of each object can be obtained through the function id(object). Therefore, the is ...
