  2. 1. Decision Algebra : A General Approach to Learning and Using Classifiers

    Author : Antonina Danylenko; Welf Löwe; Jonas Lundberg; Uwe Assmann; Linnéuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; classification; decision model; classifier; Decision Algebra; decision function; Computer Science; Datavetenskap;

    Abstract : Processing decision information is a vital part of Computer Science fields in which pattern recognition problems arise. Decision information can be generalized as alternative decisions (or classes), attributes and attribute values, which are the basis for classification. READ MORE

  4. 2. Imprecise information in multi-level decision trees

    Author : Jim Johansson [Idefeldt]; Love Ekenberg; Mittuniversitetet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; multi-level; decision tree; decision analysis; decision tool; imprecise; Computer science; Datavetenskap;

    Abstract : The information available to decision makers is often vague and imprecise, and various methods based on interval estimates of probabilities and utilities have been proposed to deal with this. The discussion has, however, mostly evolved around representation, and much less has been done to take into consideration the evaluation, and also computational and implementation aspects has been left out.

  6. 4. Predictive Health Monitoring for Aircraft Systems using Decision Trees

    Author : Mike Gerdes; Petter Krus; Diego Galar; Linköpings universitet; []
    Keywords : Condition Monitoring; Condition Prediction; Failure Prediction; Decision Trees; Genetic Algorithm; Fuzzy Decision Tree Evaluation; System Monitoring; Aircraft Health Monitoring;

    Abstract : Unscheduled aircraft maintenance causes a lot problems and costs for aircraft operators. This is due to the fact that aircraft cause significant costs if flights have to be delayed or canceled and because spares are not always available at any place and sometimes have to be shipped across the world.

  7. 5. Optimization beyond a single submodular function : Submodular optimization for ranking, decision trees and diversity

    Author : Guangyi Zhang; Aristides Gionis; Danupon Na Nongkai; Parinya Chalermsook; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Submodular optimization; Approximation algorithms; Ranking; Decision trees; Diversity; Datalogi; Computer Science;

    Abstract : Submodular functions characterize mathematically the ubiquitous ``diminishing-returns'’ property. They are widely used to describe core subjects in numerous applications, including economic utility, redundancy in information, spread of influence in social networks, and more. READ MORE
