Abstract
To comprehensively study the ginsenosides distribution in the various tissues of American ginseng, the qualitative and quantitative‐targeted and nontargeted mass spectroscopic methods were established using the high‐performance liquid chromatography coupled with Qtrap triple quadrupole mass spectrometry (HPLC‐QtrapQQQ‐MS). The total ginsenosides of the root, stem, and leaf of American ginseng...
Context-aware recommender systems try to figure out users' preferences under different context situations and have been proven to be useful in many domains. Different individual context makes different contribution to recommendation performance, but few of researchers have explored how contextual combinations influence recommendation performance. In this paper, we examine empirically the role of contextual...
Analysis of Cloud workloads using data mining technology is critical for improving resource management. Unfortunately there is a lack of systematic approach to support the feature generation in comprehensive workload analysis. In this paper we propose a function based generalized feature generation method for the analysis of a one-month trace of a Google data center over 40 million task events across...
