While some use the terms interchangeably, artificial intelligence and machine learning are not synonymous. Learn what sets these two technologies apart in ourAI vs. machine learningarticle. Top 7 Regression Algorithms in Machine Learning Various regression algorithms play a role in machine learning, fro...
Why is regression in machine learning important? Regression is an essential concept not only for machine learning experts, but also for all business leaders, as it is a foundational technique inpredictive analytics, said Nick Kramer, vice president of applied solutions at global consulting firm SSA ...
training error指模型在training set上的error。 generalization error是指模型在全体数据上的error,因为全体数据未知,所以generalization error并不知道。 test error是为了approximate generalization error,所以test set要对总体比较有代表性才行。 5.选择training set/testing set的比例的原则是什么? training set小了训练...
Logistic regression is another technique borrowed by machine learning from the field of statistics. It is the go-to method for binary classification problems (problems with two class values). In this post, you will discover the logistic regression algorithm for machine learning. After reading this ...
Linear regression is perhaps one of the most well known and well understood algorithms in statistics and machine learning. In this post you will discover the linear regression algorithm, how it works and how you can best use it in on your machine learning projects. In this post you will lear...
