Inverse halftoning by decision tree learning [PDF]

open access: possibleProceedings 2003 International Conference on Image Processing (Cat. No.03CH37429), 2004
Inverse halftoning is the process to retrieve a (gray) continuous-tone image from a halftone. Recently, machine-learning-based inverse halftoning techniques have been proposed. Decision-tree learning has been applied with success to various machine-learning applications for quite some time.

Decision Tree Learning

2016
The main objective of this chapter is to introduce you to hierarchical supervised learning models. One of the main hierarchical models is the decision tree. It has two categories: classification tree and regression tree. The theory and applications of these decision trees are explained in this chapter.

Decision tree-based paraconsistent learning

Proceedings. SCCC'99 XIX International Conference of the Chilean Computer Science Society, 2003
It is possible to apply machine learning, uncertainty management and paraconsistent logic concepts to the design of a paraconsistent learning system, able to extract useful knowledge even in the presence of inconsistent information in a database. This paper presents a decision tree-based machine learning technique capable of handling inconsistent ...

Exemplar learning in fuzzy decision trees [PDF]

open access: possibleProceedings of IEEE 5th International Fuzzy Systems, 2002
Decision-tree algorithms provide one of the most popular methodologies for symbolic knowledge acquisition. The resulting knowledge, a symbolic decision tree along with a simple inference mechanism, has been praised for comprehensibility. The most comprehensible decision trees have been designed for perfect symbolic data.

Learning probabilistic decision trees for AUC

Pattern Recognition Letters, 2006
Accurate ranking, measured by AUC (the area under the ROC curve), is crucial in many real-world applications. Most traditional learning algorithms, however, aim only at high classification accuracy. It has been observed that traditional decision trees produce good classification accuracy but poor probability estimates.

Selecting learning activities with decision trees

Proceedings of the 2012 IEEE Global Engineering Education Conference (EDUCON), 2012
Technical developments and a more and more flexible relation between working and private life lead to the inclusion of both formal and informal aspects in learning concepts, as well as supported and unsupported phases, with a flexible role of learners, tutors, and teachers.

Streaming Decision Trees for Lifelong Learning

2021
Lifelong learning models should be able to efficiently aggregate knowledge over a long-term time horizon. Comprehensive studies focused on incremental neural networks have shown that these models tend to struggle with remembering previously learned patterns.

On Lookahead Heuristics in Decision Tree Learning

2003
In decision tree learning attribute selection is usually based on greedy local splitting criterion. More extensive search quickly leads to intolerable time consumption. Moreover, it has been observed that lookahead cannot benefit prediction accuracy as much as one would hope.

On Handling Tree-Structured Attributes in Decision Tree Learning

1995
Abstract This paper studies the problem of learning decision trees when the attributes of the domain are tree-structured. We first describe two pre-processing approaches, the Quinlan- encoding and the bit-per-category methods, that re-encode the training examples in terms of new nominal attributes.
