We consider the analysis of probability distributions through their associated covariance operators from reproducing kernel Hilbert spaces. show that von Neumann entropy and relative these are intimately related to usual notions Shannon entropy, share many properties. They come together with efficient estimation algorithms various oracles on distributions. also product spaces for tensor kernels...

In this study we examine the influence of premier information systems research over time to assess the maturity of the Information Systems (IS) field and its impact on subsequent IS and non-IS research. 19,357 citations from the Social Science Citation Index (SSCI) (1982-2004) are attributed to 879 articles published in MIS Quarterly (MISQ), Information Systems Research (ISR), and the IS articl...
