摘要:Graph clustering, also known as community detection, is a long-standing problem in data mining. In recent years, with the proliferation of rich attribute information available for objects in real-world graphs, how to leverage not only structural but also attribute information for...

摘要:Current music recommender systems typically act in a greedy manner by recommending songs with the highest user ratings. Greedy recommendation, however, is suboptimal over the long term: it does not actively gather information on user preferences and fails to recommend novel songs...

摘要:In this article, we focus on solving the energy optimization problem for real-time streaming applications on multiprocessor System-on-Chip by combining task-level coarse-grained software pipelining with DVS (Dynamic Voltage Scaling) and DPM (Dynamic Power Management) considering ...

摘要:In this paper, we propose a hybrid-level flash translation layer (FTL) called RNFTL (Reuse-Aware NFTL) to improve the endurance and space utilization of NAND flash memory. Our basic idea is to prevent a primary block with many free pages from being erased in a merge operation. Th...

摘要:Different from the IP-based routers, Named Data Networking routers forward packets by content names, which consist of characters and have variable and unbounded length. This kind of complex name constitution plus the huge-sized name routing table makes wire speed name lookup an e...

摘要:Camera sensors are different from traditional scalar sensors, as cameras at different positions can form very different views of the object. However, traditional coverage model does not consider this intrinsic property of camera sensors. To address this issue, a novel model calle...

摘要:Dependencies among system components are crucial to locating root errors in a distributed system. In this paper, we propose an approach to mine intercomponent dependencies from unstructured logs. The technique requires neither additional system instrumentation nor any application...

摘要:Domain-specific optimizations on matrix computations exploiting specific arithmetic and matrix representation formats have achieved significant performance/area gains in Field-Programmable Gate Array (FPGA) hardware designs. In this article, we explore the application of dat...

摘要:NAND flash memory has been widely used to build embedded devices such as smartphones and solid state drives (SSD) because of its high performance, low power consumption, great shock resistance and small form factor. However, its lifetime and performance are greatly constrained by...

摘要:Log-block-based FTL (Flash Translation Layer) schemes have been widely used to manage NAND flash memory storage systems in industry. In log-block-based FTLs, a few physical blocks called log blocks are used to hold all page updates from a large amount of data blocks. Frequent pag...
