Classification Trees

by D.G.T. Denison, B. K. Mallick , 1998
"... The generalized linear model framework is often used in classification problems and the importance and effect of the predictor variables on the response is generally judged by examination of the relevant regression coefficients. This chapter describes classification trees which can also be used for ..."

Learning classification trees

by Wray Buntine, Wray Buntine - Statistics and Computing , 1992
"... Algorithms for learning cIassification trees have had successes in ar-tificial intelligence and statistics over many years. This paper outlines how a tree learning algorithm can be derived using Bayesian statis-tics. This iutroduces Bayesian techniques for splitting, smoothing, and tree averaging. T ..."

Split Selection Methods for Classification Trees

by Wei-Yin Loh, Yu-Shan Shih - STATISTICA SINICA , 1997
"... Classification trees based on exhaustive search algorithms tend to be biased towards selecting variables that afford more splits. As a result, such trees should be interpreted with caution. This article presents an algorithm called QUEST that has negligible bias. Its split selection strategy shares ..."

Isotonic Classification Trees

by Rémon Van De Kamp, Ad Feelders, Nicola Barile
"... Abstract. We propose a new algorithm for learning isotonic classification trees. It relabels non-monotone leaf nodes by performing the isotonic regression on the collection of leaf nodes. In case two leaf nodes with a common parent have the same class after relabeling, the tree is pruned in the pare ..."

Classification Tree Sources

by Edgar Binder, Manfred Kufleitner
"... Abstract—The separation of source coding into two stages, modeling and encoding, is a highly successful approach. We propose meta-modeling as an additional stage. As an application, we use this paradigm to deduce an efficient and optimal algorithm for a novel and powerful model set: the classificati ..."

: the classification tree sources. Our results on classification tree sources unify and generalize prior results for tree sources. Moreover, we point out applications in text and image compression. I.

Pruning for monotone classification trees

by Ad Feelders, Martijn Pardoel - Lecture Notes in Computer Science
"... Abstract. For classification problems with ordinal attributes very often the class attribute should increase with each or some of the explanatory attributes. These are called classification problems with monotonicity constraints. Standard classification tree algorithms such as CART or C4.5 are not g ..."

Model-Based Classification Trees

by Donald Geman, Bruno Jedynak - IEEE Transactions on Information Theory , 1998
"... The construction of classification trees is nearly always top-down, locally optimal and data-driven. Such recursive designs are often globally inefficient, for instance in terms of the mean depth necessary to reach a given classification rate. We consider statistical models for which exact global op ..."

IMPROVING THE PRECISION OF CLASSIFICATION TREES

by Wei-yin Loh , 2009
"... Besides serving as prediction models, classification trees are useful for finding important predictor variables and identifying interesting subgroups in the data. These functions can be compromised by weak split selection algorithms that have variable selection biases or that fail to search beyond l ..."

A Classification Tree for Speciation

by Alain Petrowski, Marc Girod, Marc Girod Genet, Departement Informatique, Departement Informatique - In Proceedings of CEC 1999 , 1999
"... The most efficient speciation methods suffer from a quite high complexity from O(n c(n)) to O(n 2 ), where c(n) is a factor that can be proportional to n, the population size. In this paper, a speciation method based on a classification tree is presented, having a complexity of O(n log n). The pop ..."

Diversification for better classification trees.

"... Abstract Classification trees are widely used in the data mining community. Typically, trees are constructed to try and maximize their mean classification accuracy. In this paper, we propose an alternative to using the mean accuracy as the performance measure of a tree. We investigate the use of va ..."
