Classification and Regression in Machine Learning

Both classification and regression in machine learning deal with the problem of mapping a function from input to output. However, when it comes to classification problems, the output is a discrete (non-continuous) class label or categorical output. While on the other hand, when the problem is a regression problem, the output is continuous. Support Vector Machine in Machine Learning (ML)
