Kullback-Leibler cross-entropy has unique properties in cases involving distributions resulting from cross-entropy minimization. Nonextensive entropy (Tsallis entropy), which is a one-parameter generalization of Shannon entropy, is proposed to study certain class of physical systems. Thermostatistics based on Tsallis entropy is termed as nonextensive(More)
Most of the existing academic social networks like DBLP and ArnetMiner suggest co-authors as being related to each author based on author and co-author details, which are extracted from academic researchers publications. Instead of this approach, we propose grouping of researchers on basis of topics they have in common that would make more semantic sense(More)

In this paper radix-2 algorithms for computation of type-II discrete cosine transform (DCT) and discrete sine transform (DST) of length N = 2 (n ≥ 2) are presented. The DCT/DST can be computed from two DCT/DST sequences, each of length N/2. The odd-indexed output components of DCT/DST can be realized using simple recursive relations. The proposed algorithms(More)
In this paper, novel recursive algorithms for realization of one-dimensional discrete sine transform (DST) and inverse discrete sine transform (IDST) of any length are proposed. By using some mathematical techniques, recursive expressions for DST and IDST have been developed. Then, the DST and IDST are implemented by recursive filter structures. A linear(More)
