Machine Learning: An In-Depth Guide – Unsupervised Learning, Related Fields, and Machine Learning in Practice

Welcome to the fifth and final article in a five-part series about machine learning. In this final article, we will revisit unsupervised learning in greater depth, briefly discuss other fields related to machine learning, and finish the series with some examples of real-world machine learning applications. Recall that unsupervised learning involves learning from data, but without the goal of prediction. This is because the data is either not given with a target response variable (label), or one chooses not to designate a response. It can also be used as a pre-processing step for supervised learning.
