Flexible document organization: comparing fuzzy and possibilistic approaches
(Institute of Electrical and Electronics Engineers - IEEEIstanbul, 2015-08)
System flexibility means the ability of a system to manage imprecise and/or uncertain information. A lot of commercially available Information Retrieval Systems (IRS) address this issue at the level of query formulation. ...
Evolving Possibilistic Fuzzy Modeling For Realized Volatility Forecasting With Jumps

An evolving possibilistic fuzzy modeling approach for value-at-risk estimation
(2016-02)
Market risk exposure plays a key role for nancial institutions risk management. A possible measure for this exposure is to evaluate losses likely to incurwhen the price of the portfolio's assets declines using Value-at-Risk ...

An improvement to the possibilistic fuzzy c-means clustering algorithm
(2007)
In this work we propose to use the Gustafson-Kessel (GK) algorithm within the PFCM (Possibilistic Fuzzy c-Means), such that the cluster distributions have a better adaptation with the natural distribution of the data. The ...

Comparing hard and overlapping clusterings
(MicrotomeBrookline, 2015-12)
Similarity measures for comparing clusterings is an important component, e.g., of evaluating clustering algorithms, for consensus clustering, and for clustering stability assessment. These measures have been studied for ...
Image segmentation by fuzzy and possibilistic clustering algorithms for the identification of microcalcifications
(2011)
Breast cancer is one of the leading causes of female mortality in the world, and early detection is an important means of reducing the mortality rate. The presence of microcalcification clusters has been considered as a ...
