Machine learning

Machine learning is one of the advanced analytics that harness data. Machine learning is a collection of algorithms that helps people to understand data in many different ways. These algorithms can be categorized into two categories:

• Supervised learning: Supervised-learning algorithms are some of the most commonly used machine learning algorithms. They use historical data to train a machine- learning model. These algorithms can be further categorized into classification and regression algorithms. In classification algorithms, the model is trained to predict a categorical/discrete dependent variable. One of the basic examples is predicting whether an email is spam. On the other hand, regression algorithms predict continuous ...
