Many association studies analyze the genotype frequencies of case and control data to predict susceptibility to diseases and cancers. Without providing the raw data for genotypes, many association studies cannot be interpreted fully. Often, the interactions of the single nucleotide polymorphisms (SNPs) are not addressed and this limits the potential of such(More)
The feature selection process can be considered a problem of global combinatorial optimization in machine learning, which reduces the number of features, removes irrelevant, noisy and redundant data, and results in acceptable classification accuracy. In this study, we propose a combined filter method (ReliefF) and a wrapper method (memetic algorithm, MA)(More)
Efficiency for mobile devices becomes important than ever due to the demanding multimedia applications. Take HD video decoding for example, it is getting challenging as the resolution increases. To enhance efficiency, HSA (Heterogeneous System Architecture) is proposed to drive a new era of computation. Based on this idea, we develop a heterogeneous(More)
Thread divergence frequently occurs in various GPGPU applications while parallel threads encounter branching, especially for multimedia algorithms involving high-level image processing and computer vision algorithms. Either predicate or branch instruction degrades the parallel processing performance as a result of synchronization cost. In this work, we(More)
In a remote rendering system, the display device and the main graphics processing unit (GPU) are located in different places, which is a kind of client-server architecture and is widely used in cloud gaming and virtual reality (VR). To reduce the in­ teraction delay and improve the user experience especially when the link between the server and client(More)
Today 2.4 GHz based wireless sensor networks are increasing at a tremendous pace, and are seen in widespread applications. Product innovation and support by many vendors in 2.4 GHz makes it a preferred choice, but the networks are prone to issues like interference, and range issues. On the other hand, the less popular 868 MHz in the ISM band has not seen(More)
