Classification
Classification is the use of a modeling process to assign classes to data.
Class Identifiers
Class identifiers are related to Machine Learning applications, such as:
Object Recognition - person, bicycle, car, sign
Churn Prediction - low, medium, high
Credit Scoring - score numbers
Handwritten Numbers - digits
Data
Data is used to measure features of of observation instances.
Modeling Process
The Modeling Process is used to train models to perform classification predictions.
Classified Data
Data describing features related to specific observations is classified, such as:
Object Recognition - bicycle
Churn Prediction - high
Credit Scoring - 810
Handwritten Numbers - 7
Classification vs. Regression
Classification produces discrete category predictions. Regression produces continuous number predictions.
