I highly recommend to take the Machine Learning course by Andrew Ng. In the following article, I want to guide you through the theory and implementation of logistic regression with gradient descent in JavaScript. For instance, a set of articles could be classified into different topics such as web development, machine learning or software engineering.Īn algorithm that could be used to solve a classification problem is called logistic regression. However, a classification problem can be extended to a multiclass classification problem going beyond the binary classification. The output would be a binary dependent variable, because it can be either 0 or 1. For instance, a classification problem could be to separate spam emails from useful emails or to classify transactions into fraudulent and not fraudulent. In contrast, in a classification problem an algorithm is trained to predict categorical values. This article doesn't recap those topics but applies them for logistic regression to solve a classification problem in JavaScript. Checkout the recent articles to understand the foundational knowledge about linear regression including the essential cost function and hypothesis to perform the gradient descent algorithm. Afterward, the algorithm can predict housing prices for houses not included in the training set. The algorithm is trained by using a training set. It can be housing prices in a specific area based on a feature set such as square meters or numbers of bedrooms. In a regression problem, an algorithm is trained to predict continuous values. A couple of my recent articles gave an introduction to machine learning in JavaScript by solving regression problems with linear regression using gradient descent or normal equation. ![]()
