Class-based reducts in DRSA

2010 Seventh International Conference on Fuzzy Systems and Knowledge Discovery, 2010
In an ordered decision information system, dominance-based rough set approach (DRSA) were used to compute reducts of the system which preserve the lower and upper approximations of upward union and downward union of decision classes. Recently, class-based reducts (L-reduct and U-reduct) which preserve respectively lower and upper approximates of each ...

A fuzzy set extension of DRSA on the better life in happiness

2012 International conference on Fuzzy Theory and Its Applications (iFUZZY2012), 2012
The desire of human beings and the goal of government policy basically have a common point, i.e., the better life in happiness. However, the common point composed of multi-criteria from objective and subjective living causes difficulty in decision making. This research applies the fuzzy set extensions of dominance-based rough set approach (FSE-DRSA) on

On Performance of DRSA-ANN Classifier

Lecture Notes in Computer Science, 2011
Rule-based and connectionist classifiers are typically named as two different approaches to recognition tasks. The first relies on induction of a set of rules that list conditions to be met for a decision to be applicable, while the latter means distribution of data and processing.

Incremental method of updating approximations in DRSA under variations of multiple objects

International Journal of Machine Learning and Cybernetics, 2015
Dominance-based rough sets approach (DRSA) uses dominance relations to substitute equivalence relations in conventional rough set models so that it can handle preference-ordered information. Up to date, DRSA has been widely used in multi-criteria decision-making problems.

VC-DRSA for knowledge retrieval based on technical analysis and investment practice

2014 International Conference on Fuzzy Theory and Its Applications (iFUZZY2014), 2014
This study aims to retrieve useful knowledge from commonly adopted technical indicators, based on a soft computing model, to support investment decisions. Though the validity of technical analysis (TA) has been examined extensively by various statistical models in financial literature, a practical approach that may consider the inconsistency among ...

DRSA Decision Algorithm Analysis in Stylometric Processing of Literary Texts

Lecture Notes in Computer Science, 2010
When the indiscernibility relation, fundamental to Classical Rough Set Approach, is substituted with dominance relation, it results in Dominance-Based Rough Set Approach to data analysis. It enables support not only for nominal classification tasks, but also when ordinal properties on attribute values can be observed [1], making DRSA methodology well ...

A refined DRSA model for the financial performance prediction of commercial banks

2013 International Conference on Fuzzy Theory and Its Applications (iFUZZY), 2013
In this study, an integrated soft computing method is proposed to solve the performance prediction of commercial banks. The proposed model not only shows how to explore the implicit patterns from historical data, but also supports to provide guidance regarding the performance categorization of banks on each attribute.

On Preference Order of DRSA Conditional Attributes for Computational Stylistics

Lecture Notes in Computer Science, 2013
Computational stylistics (or stylometry) advocates that any writing style can be uniquely defined by quantitative measures. The patterns observed in textual descriptors are specific to authors in such high degree that it enables their recognition. In processing there can be employed techniques from artificial intelligence domain such as Dominance-Based

Application of DRSA-ANN Classifier in Computational Stylistics

Lecture Notes in Computer Science, 2011
Computational stylistics or stylometry deals with characteristics of writing styles. It assumes that each author expresses themselves in such an individual way that a writing style can be uniquely defined and described by some quantifiable measures. With help of contemporary computers the stylometric tasks of author characterisation, comparison, and ...

Fuzzy Inference-Enhanced VC-DRSA Model for Technical Analysis: Investment Decision Aid

International Journal of Fuzzy Systems, 2015
To support investment decision based on technical analysis (TA), this study aims to retrieve the knowledge or rules of various indicators by a hybrid soft computing model. Although the validity of TA has been examined extensively by various statistical methods in literature, previous studies mainly explored the effectiveness of each technical indicator
