+## Multiclass classification
 
 A [supervised machine learning](glossary.md#supervised-machine-learning) task that is used to predict the class (category) of an instance of data. The input of a classification algorithm is a set of labeled examples. Each label is an integer between 0 and k-1, where k is the number of classes. The output of a classification algorithm is a classifier, which you can use to predict the class of new unlabeled instances. Examples of multi-class classification scenarios include:
 
 * Determining the breed of a dog as a "Siberian Husky", "Golden Retriever", "Poodle", etc.
 * Understanding movie reviews as "positive", "neutral", or "negative".
 * Categorizing hotel reviews as "location", "price", "cleanliness", etc.

 ## Regression
 
 A [supervised machine learning](glossary.md#supervised-machine-learning) task that is used to predict the value of the label from a set of related features. The label can be of any real value and is not from a finite set of values as in classification tasks. Regression algorithms model the dependency of the label on its related features to determine how the label will change as the values of the features are varied. The input of a regression algorithm is a set of examples with labels of known values. The output of a regression algorithm is a function, which you can use to predict the label value for any new set of input features. Examples of regression scenarios include:
