Machine learning is a field of study that looks at and constructs algorithms that can learn from and make predictions on experimental data. There are two major classes of machine learning: supervised and unsupervised.

Supervised learning attempts to infer a predictive function from a labeled training data set—a data set where each observation is known to belong to a certain class (the classification is in fact a part of the data set). We’ll take a look at linear regression, including logistic regression in Unit 49, ​Fitting a Linear Regression​, and at random decision forests in Unit 51, ​Surviving in Random Decision Forests ...
