Despite numerous studies demonstrating that authoritarian leadership and benevolent leadership exert incompatible influence on an individual’s creativity, the combined effects of authoritarian leadership and benevolent leadership on an individual’s creativity and the related mechanisms have yet to be explained. This study tests a model that considers the combined effects of authoritarian and benevolent...
Kernel methods and Nonnegative matrix factorization (NMF) are both widely used in data mining and machine learning. The previous one is best known for its capability of transforming data into high dimension feature space, while the latter one is well known for its natural interpretations and good performance. In this paper, we propose a robust kernel NMF approach using L2, 1 norm loss function. Compared...
In this paper, we integrate symmetric NMF and normalized cut into a single clustering framework and derive the computational algorithm. Another contribution is to provide a new matrix inequality which is useful for the analysis of 4-th order matrix polynomials. We perform experiments on three real-life data sets to show the effectiveness of the proposed algorithm. We also demonstrate the importance...
