## ant colony optimization

Overview page. Subjects: Computing — Probability and Statistics.

An optimization procedure that seeks to mimic an ant's apparent ability to find the shortest distance between two points. The ant's choices are based on the quantities of pheromones left by...

## bump hunting

Overview page. Subjects: Probability and Statistics.

A term apparently originated by experimental physicists and now used in data mining. It refers to the problem of finding clustered values in multivariate data.

## classification tree

Overview page. Subjects: Probability and Statistics.

A rule for predicting the class of an object from the values of its predictor variables. Classification trees are much used in data mining. They differ from discriminant analysis in that...

## particle swarm optimization

Overview page. Subjects: Computing.

An optimization technique used in data mining that attempts to find some optimal solution from a large space of possible solutions. It gets its name from the fact that a number of possible...

## simulated annealing

Overview page. Subjects: Computing.

A technique used in data mining to select an optimal set of data from a large space of solutions. The term comes from the fact that the techniques uses a process similar to that found when...
