Non-monotone projection gradient method for non-negative matrix factorization
Since Non-negative Matrix Factorization (NMF) was first proposed over a decade ago, it has attracted much attention, particularly when applied to numerous data analysis problems. Most of the existing algorithm...

Modified subspace Barzilai-Borwein gradient method for non-negative matrix factorization
Non-negative matrix factorization (NMF) is a problem to obtain a representation of data using non-negativity constraints. Since the NMF was first proposed by Lee, NMF has attracted much attention for over a de...

Evaluating entity-description conflict on duplicated data
Duplicated records, which describe the same entity in the real world, frequently generated by data integration. Ideally, the values on the same attributes of duplicated records should be identical. However, th...

On the residual closeness of graphs with cut vertices
In designing and understanding of computer networks, how to improve network robustness or protect a network from vulnerability remains an overarching concern. The residual closeness is a measure of network vul...
