Auction-Based Order-Matching Mechanisms to Maximize Social Welfare in Real-Time Ride-Sharing slight sacrifice of social welfare. We theoretically prove that both mechanisms satisfy the properties such as truthfulness, individual rationality, profitability and so on. We then evaluate the performance of both mechanisms in the real taxi order data in New York city and demonstrate that our mec

GDS: General Distributed Strategy for Functional Dependency Discovery Algorithmst-FD sets of data blocks satisfy FD-Combine induction condition. With our strategy, each single-node FD discovery algorithm can be directly parallelized without modification in distributed environments. In the evaluation, with . threads, the speedups of FD discovery algorithm FastFDs exceed . in mos

Low-Latency Hardware Masking of PRINCEion method allows different replicas to be logically identical while having different physical data layouts on the disk. We verified the efficiency of our method in a NoSQL system, Cassandra, with the TPC-H dataset and with a synthetically generated dataset. The results show that our method outperfo

We prove that algorithm

Our scheme can be applied on all type of numerical attributes (e.g. Integer, float, double, boolean). In robust experiments, the scheme is proved to be extremely resilient to insert

To reduce the effect of noise, we formulate the parametric estimation problem with a multi-layer latent variables structure, and utilize Expectation-Maximization algorithm to solve the Gaussian Mixture Model.

We also introduce the concept that the representation of multimedia data can be separated into content and style manner. The modality representation codes are employed to improve the effectiveness of the generative adversarial learning. Extensive experimen
