The problem of modeling complex processes with a large number of inputs is addressed. A new method is proposed for the optimization of the models in minimum C(p) statistic sense using QR with a modified scheme of column pivoting (m-QRcp) factorization. Two different classes of multilayer nonlinear modeling problems are explored: 1) in the first class of… (More)
In India, most of the commercial transport is being carried out by the railway network and therefore, any problems in the same has the capacity to induce major damage to the economy-notwithstanding the societal impact of loss of life or limb. This paper proposes a cost effective yet robust solution to the problem of railway crack detection utilizing a… (More)
Beginning with a critical analysis of existing multimedia metrics, this paper builds upon their drawbacks in streaming media by the introduction of alternate metrics, backed by analytical correctness proofs of accuracy and comparative simulation with earlier metrics to justify the improvements made in security judgement techniques.
