a system which classifies given instance in one of N possible classes

a wildcard filter that matches every packet not otherwise matched

an entity which selects packets based on the content of packet headers according to defined rules.

(also: filter or tcf) classifies a network packet by inspecting it, used by QDiscs.

A predictive model that attempts to describe one column (the label) in terms of others (the attributes). A classifier is constructed from data where the label is known, and may be later applied to predict label values for new data where the label is unknown. Internally, a classifier is an algorithm or mathematical formula that predicts one discrete value for each input row. For example, a classifier built from a dataset of iris flowers could predict the type of a presented iris given the length and width of its petals and stamen). Classifiers may also produce probability estimates for each value of the label. For example, a classifier built from a dataset of cars could predict the probability that a specific car was built in the United States. Classifiers only work with discrete labels. A Regressor is the analog of a Classifier for continuous labels.

Method of reading a sequence of bits in a packet header or label and determining how the packet should be forwarded internally and scheduled (queued) for output.

In mathematics, a classifier is a mapping from a (discrete or continuous) feature space X to a discrete set of labels Y.

a namespace whose members can include features

Module that matches features of a recording against the prototypes of one or more learned persons. Also calculates the prototypes from training data.

A UML element that has Attributes and Operations. Specifically, Actors, Classes, and Interfaces.

A classifier is a category of UML elements that have some common features, such as attributes or methods.

A set of production rules used to match environmental data and suggest an action to be taken, usually incorporates a genetic algorithm. Each rule covers part of state space.

A rule that is part of a classifier system and has a condition that must be matched before its message (or action) can be posted (or effected). The strength of a classifier determines the likelihood that it can outbid other classifiers if more than one condition is matched.
