Distributionally Robust Multi-Output Regression Ranking
Shahabeddin Sotudian, Ruidi Chen, Ioannis Paschalidis
Despite their empirical success, most existing listwiselearning-to-rank (LTR) models are not built to be robust to errors in labeling or annotation, distributional data shift, or a…
Interval Type-2 Enhanced Possibilistic Fuzzy C-Means Clustering for Gene Expression Data Analysis
Shahabeddin Sotudian, Mohammad Hossein Fazel Zarandi
Both FCM and PCM clustering methods have been widely applied to pattern recognition and data clustering. Nevertheless, FCM is sensitive to noise and PCM occasionally generates coin…
A New Validity Index for Fuzzy-Possibilistic C-Means Clustering
Mohammad Hossein Fazel Zarandi, Shahabeddin Sotudian, Oscar Castillo
In some complicated datasets, due to the presence of noisy data points and outliers, cluster validity indices can give conflicting results in determining the optimal number of clus…
