This paper summarizes four popular machine learning algorithms

This paper not only tries to explain the working principle of the algorithm, but also intuitively understand the working principle of the algorithm to provide this kind of light bulb Aha! The moment. Decision tree The decision tree uses horizontal and vertical lines to divide the feature space. For example, consider the following very simple […]

Scope and algorithm of machine learning

What is machine learning? Machine learning is a literal translation of the English name machine learning (ML). Machine learning involves probability theory, statistics, approximation theory, convex analysis, algorithm complexity theory and other disciplines. It focuses on how computers simulate or realize human learning behaviors, so as to acquire new knowledge or skills, reorganize the existing […]

Skill sharing of machine learning algorithm

1. C parameter of support vector machine (SVM) The C parameter of SVM increases the cost for each misclassified data point. If C is small, the penalty for misclassification points is low, so the decision boundary with large margin is selected at the cost of a large number of misclassification. If C is large, SVM […]

Key points of seven machine learning algorithms

1. Support vector machine (SVM) Key point: C parameter SVM creates a decision boundary to distinguish two or more classes. Soft margin support vector machine tries to solve the optimization problem with the following objectives Increasing the distance between decision boundary and class (or support vector) Maximize the number of points correctly classified in the […]

Apple watch can predict diabetes

Before modern medicine brought advanced blood and urine tests, doctors had to rely on taste buds to diagnose diabetes. Sweetness in urine has always been the most significant pathological feature of diabetes. The literal meaning of mellitus is “sweet”. Too much sugar in your body fluids means that there is something wrong with your metabolism, […]
