Techniques for simplifying decision trees while retaining their accuracy are discussed, described, illustrated, and compared on a test-bed of decision trees from a variety of domains.
Abstract
Many systems have been developed for constructing decision trees from collections of examples. Although the decision trees generated by these methods are accurate and efficient, they often suffer the disadvantage of excessive complexity and are therefore incomprehensible to experts. It is questionable whether opaque structures of this kind can be described as knowledge, no matter how well they function. This paper discusses techniques for simplifying decision trees while retaining their accuracy. Four methods are described, illustrated, and compared on a test-bed of decision trees from a variety of domains.

Machine learnt image processing to predict weight and size of rice kernels

TL;DR: A novel methodology is proposed that combines image processing and machine learning (ML) ensemble to accurately measure the size and mass of several rice kernels simultaneously to facilitate head rice yield quantifications and promote quicker rice quality appraisals.

Using the ID3 algorithm to find discrepant diagnoses from laboratory databases of thyroid patients.

TL;DR: In simple medical classification tasks this dynamic self- learning system can be used to create a DSS that can assist in the quality control of clinical decision making and in clinical situations about 5-10% of functional thyroid disorders may be misclassified.

Effects of meteorological forcing on coastal eutrophication: modeling with model trees

TL;DR: In this article, the authors used model trees (MTs), a machine learning (ML) approach whereby linear regressions are induced within homogeneous subsets of samples (tree leaves).

Spatial prediction of shallow landslide: application of novel rotational forest-based reduced error pruning tree

TL;DR: In this paper, the authors investigate landslide rates and behaviour and find that landslides are a form of soil erosion threatening the sustainability of some areas of the world and there is a need to investigate landslide rate and behaviour.

A brain tumor diagnostic system with automatic learning abilities

TL;DR: A medical diagnostic system, BTDS (the brain tumors diagnostic system), is presented and the proposed learning mechanism, based on a revised inductive learning method, is presented, which can help diagnosticians in judging the causes of brain tumors according to computed tomography pictures.

Induction of Decision Trees

J. R. Quinlan
- 25 Mar 1986 - 
TL;DR: In this paper, an approach to synthesizing decision trees that has been used in a variety of systems, and it describes one such system, ID3, in detail, is described, and a reported shortcoming of the basic algorithm is discussed.

Pattern-directed inference systems

TL;DR: In this paper, the authors discuss a crop identification and acreage estimation case study, followed by rather brief discussions of five selected management problems: large area land use inventory and forest, snow-cover, geologic, and water-temperature mapping.
