Dimensionality reduction of big data is becoming more and more important in many domains, such as cloud computing, human gene distribution, image processing and smart grids, which all involve high-dimensional data analysis. While traditional linear dimensionality reduction techniques are computationally efficient and simple to implement, they fail to adequately capture the intrinsic structure of complex...
Existing conventional RAID storage systems are unable to provide expected storage performance under the explosive growth in data volumes. One of the solution is introducing SSDs (Solid State Drives), a promising storage medium which provides high performance and power efficiency, as a cache to loosen the performance bottleneck of RAID storage systems. However, using DRAM as a universe buffer area...
