Feature selection simultaneously preserving both class and cluster structures
Suchismita Das, Nikhil R. Pal
When a data set has significant differences in its class and cluster structure, selecting features aiming only at the discrimination of classes would lead to poor clustering perfor…
Understanding the classes better with class-specific and rule-specific feature selection, and redundancy control in a fuzzy rule based framework
Suchismita Das, Nikhil R. Pal
Recently, several studies have claimed that using class-specific feature subsets provides certain advantages over using a single feature subset for representing the data for a clas…
Nonlinear Dimensionality Reduction for Data Visualization: An Unsupervised Fuzzy Rule-based Approach
Suchismita Das, Nikhil R. Pal
Here, we propose an unsupervised fuzzy rule-based dimensionality reduction method primarily for data visualization. It considers the following important issues relevant to dimensio…
Morphological transitions of active Brownian particle aggregates on porous walls
Suchismita Das, Raghunath Chelakkot
Motility-induced wall aggregation of active Brownian particles (ABPs) is a well-studied phenomenon. Here, we study the aggregation of ABPs on porous walls, which allows the particl…
Aggregate morphology of active Brownian particles on porous, circular walls
Suchismita Das, Sounok Ghosh, Raghunath Chelakkot
We study the motility-induced aggregation of active Brownian particles (ABPs) on a porous, circular wall. We observe that the morphology of aggregated dense-phase on a static wall…
Some Ageing Properties of Dynamic Additive Mean Residual Life Model
Suchismita Das, Asok K. Nanda
Although proportional hazard rate model is a very popular model to analyze failure time data, sometimes it becomes important to study the additive hazard rate model. Again, sometim…
