Mining stock price using fuzzy rough set system

YF Wang - Expert Systems with Applications, 2003 - Elsevier
In this study of mining stock price data, we attempt to predict the stronger rules of stock
prices. To address this problem, we proposed an effective method, a fuzzy rough set system …

SAINTETIQ: a fuzzy set-based approach to database summarization

G Raschia, N Mouaddib - Fuzzy sets and systems, 2002 - Elsevier

Data mining by attribute generalization with fuzzy hierarchies in fuzzy databases

FE Petry, L Zhao - Fuzzy Sets and Systems, 2009 - Elsevier
In this paper we examine the soft computing issues involving data generalization on fuzzy
information. The attribute induction process is formalized for these three cases: crisp …

A new method for computing fuzzy functional dependencies in relational database systems

M Vucetic, M Hudec, M Vujošević - Expert Systems with Applications, 2013 - Elsevier
