Unsupervised Learning versus Supervised Learning

Unsupervised learning is one of the most exciting areas of development in machine learning today. If you have explored machine learning bookwork before, you are probably familiar with the common breakout of problems in either supervised or unsupervised learning. Supervised learning encompasses the problem set of having a labeled dataset that can be used to either classify (for example, predicting smokers and non-smokers if you're looking at a lung health dataset) or fit a regression line on (for example, predicting the sale price of a home based on how many bedrooms it has). This model most closely mirrors an intuitive human approach to learning.

If you wanted to learn how to not burn your food with a basic understanding of cooking, you could build a dataset by putting your food on the burner and seeing how long it takes (input) for your food to burn (output). Eventually, as you continue to burn your food, you will build a mental...
