The problem of mobile sequential recommendation is to suggest a route connecting a set of pick-up points for a taxi driver so that he/she is more likely to get passengers with less travel cost. Essentially, a key challenge of this problem is its high computational complexity. In this paper, we propose a novel dynamic programming based method to solve the mobile sequential recommendation problem consisting...
In distributed storage systems, a data file is encoded and distributed to storage nodes, such that the data file can be recovered from some subsets of the nodes. Upon the failure of a storage node, we want to repair it efficiently by contacting and downloading some encoded bits from a small number of surviving nodes. Using projective-geometric self-repairing codes (PSRC), proposed by Oggier and Datta,...
In order to solve problems as high error diffusion and instable convergence of Recursive Least Squares (RLS) algorithm in Code Division Multiple Access (CDMA), this paper combined local steepest drop characteristic of steepest descent algorithm presented a stable convergence and lower complexity algorithm -- D-RLS in condition of high multiple access interference (MAI) and intersymbol interference...
