Maximum-likelihood estimationis a common learning algorithm used by a variety of machine learning algorithms, although it does make assumptions about the distribution of your data (more on this when we talk about preparing your data). The best coefficients would result in a model that would predic...
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...
Regression inmachine learningis a technique used to capture the relationships between independent and dependent variables, with the main purpose of predicting an outcome. It involves training a set ofalgorithmsto reveal patterns that characterize the distribution of each data point. With patterns identifi...

Machine Learning Projects Challenges Winning Approach Transfer Learning Practical Guide to Logistic Regression Analysis in R Problems Tutorial IntroductionRecruiters in the analytics/data science industry expect you to know at least two algorithms: Linear Regression and Logistic Regression. I...
Machine learning models need to generalize well to new examples that the model has not seen in practice. In this module, we introduceregularization, which helps prevent models fromoverfittingthe training data. 到现在为止 你已经见识了 几种不同的学习算法包括线性回归和逻辑回归它们能够有效地解决许多问题...
logistic regression,在英语的术语里准确而简洁,但是翻译成中文则有多种译法,例如:逻辑回归(比较常见),对数几率回归(周志华),逻辑斯谛回归(Understanding Machine Learning:From Theory to Algorithms中译本)等等,个人比较喜欢周老师的翻译,从名称中可以看到背后的意义。(后文都采用此译法) ...
In this post, we aim to give an intuitive explanation for why machine learning algorithms struggle with imbalanced data, show you how to quantify the performance of your algorithm using quantile evaluation, and show you three different strategies to improve your algorithm’s performance....
