Recommender systems have made significant progress over the last decade and several industrial-strength systems have been developed. Typically, recommender systems try to predict people's preferences and use accuracy indices such as mean absolute error to judge the performance of the algorithms. Recently, the diversity index is widely accepted as another metric. However, the ability of a recommendation...
Prediction of wireless network conditions enables the reconfiguration of mobile applications in a varying network environment, which in turn might gain more energy savings and better quality of service. In this paper, we focus on the prediction of network signal strength and its potential of improving energy saving in network-based power adaptations. We evaluate the performance of three prediction...
In the past decades, regression approach was a main gene mapping method. For avoiding the QTL mapping to estimate the gene effects, the molecular marker regression was used to research the quantitative trait controlled by polygene under the condition of complete linkage between gene locus and marker. For the utilization of this method, the recombination influence on precision and accuracy estimating...
In the past, the gene effect causing the variation of quantitative trait was researched as a whole body. For avoiding the QTL mapping, the molecular marker regression was used to research the quantitative trait controlled by polygene. A general analysis model using molecular marker material was established for estimating the gene effect controlling quantitative trait, and the mathematical relation...
