An affine equivariant version of multivariate median is introduced. The proposed median is easy to compute and has some appealing geometric features that are related to the configuration of aâ€¦ (More)

In this paper, we consider a large class of computational problems in robust statistics, which can be formulated as selection of optimal subsets of data based on some criterion function. To solveâ€¦ (More)

In this paper, we provide a general formulation for the problems that arise in the computation of many robust and nonparametric estimates in terms of a combinatorial optimization problem. There isâ€¦ (More)

Most of the clustering algorithms available in the literature require the number of clusters to be fixed a priori. That makes the determination of the number of clusters a very important problem inâ€¦ (More)

Design space exploration is central to embedded system design. Typically this is a multi-objective search problem, where performance, power, area etc. are the different optimization criteria, to findâ€¦ (More)

A mathematical model based coking control system has been developed and implemented at coke oven battery no. 3 of Bhilai Steel Plant, Steel Authority of India Ltd., India. The mathematical modelâ€¦ (More)

The univariate quantile-quantile (Q-Q) plot is a well-known graphical tool for examining whether two data sets are generated from the same distribution or not. It is also used to determine how well aâ€¦ (More)
