unsupervised learningSummary This chapter is about techniques for studying the latent structure of our data, in situations where we do not know a priori what it should look like. They are often called "unsupervised" learning because, unlike classification and regression, the "right answers" are ...

Data science and ML models typically come with three unique approaches: unsupervised learning, supervised learning and semi-supervised learning. The following are some unique features and differences between these approaches: Supervised learning is an ML technique similar to unsupervised learning, but in ...
Association rule learning identifies interesting relations between variables in large databases. For example, in transactional data, association rules can be used to identify which items are most likely to be bought together by the users. Algorithms used in association rule mining include: Apriori algo...
What Is Unsupervised Learning? In the world ofartificial intelligenceand data science, different methodologies carry out a variety of tasks. These methodologies, designed to process, analyze, and draw insights from data, represent some of the most critical underpinnings of theAI and machine learningre...
Unsupervised learning refers to data science approaches that involve learning without a prior knowledge about the classification of sample data. In Wikipedia, unsupervised learning has been described as “the task of inferring a function to describe hidden structure from ‘unlabeled’ data (a classificat...
K-Means clustering is one of the most commonly used unsupervised learning algorithms in data science. It is used to automatically segment datasets into clusters or groups based on similarities between data points. In this short tutorial, we will learn how the K-Means clustering algorithm works and...
