A Complex Network Approach for Collaborative Recommendation
Ranveer Singh, Bidyut Kr. Patra, Bibhas Adhikari
Collaborative filtering (CF) is the most widely used and successful approach for personalized service recommendations. Among the collaborative recommendation approaches, neighborho…
Self-Coordinated Corona Graphs: a model for complex networks
Rohan Sharma, Bibhas Adhikari
Recently, real world networks having constant/shrinking diameter along with power-law degree distribution are observed and investigated in literature. Taking an inspiration from th…
Structural and Spectral properties of Corona Graphs
Rohan Sharma, Bibhas Adhikari, Abhishek Mishra
Product graphs have been gainfully used in literature to generate mathematical models of complex networks which inherit properties of real networks. Realizing the duplication pheno…
A graph theoretical approach to states and unitary operations
Supriyo Dutta, Bibhas Adhikari, Subhashish Banerjee
Building upon our previous work, on graphical representation of a quantum state by signless Laplacian matrix, we pose the following question. If a local unitary operation is applie…
Structured inverse least-squares problem for structured matrices
Bibhas Adhikari, Rafikul Alam
Given a pair of matrices X and B and an appropriate class of structured matrices S, we provide a complete solution of the structured inverse least-squares problem $min_{A\in_S} \|A…
Context dependent preferential attachment model for complex networks
Pradumn Kumar Pandey, Bibhas Adhikari
In this paper, we propose a growing random complex network model, which we call context dependent preferential attachment model (CDPAM), when the preference of a new node to get at…
