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...
By Jason Brownlee on December 6, 2023 in Machine Learning Algorithms 136 Share Post Share 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...
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...

To evaluate the performance of machine learning (ML) models and to compare it with logistic regression (LR) technique in predicting cognitive impairment related to post intensive care syndrome (PICS-CI). We conducted a prospective observational study of
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....
