The modern image search system requires semantic understanding of image, and a key yet under-addressed problem is to learn a good metric for measuring the similarity between images. While deep metric learning has yielded impressive performance gains by extracting high level abstractions from image data, a proper objective loss function becomes the central issue to boost the performance. In this paper,...
With the prosperity and popularity of social tagging communities, developing an enormous amount of user-generated data with modalities has emerged in recent years. Personalized search based on tag-based profiles, an indispensable and prominent way to assist users to access and retrieve their interested resources, has been extensively studied by research communities. In this paper, we revisit the extant...
A principle motivation for the development of early-stage shipboard power system simulation techniques is the need to perform time-domain simulation during the early design stage. In particular, there is a need to understand the performance of a candidate system during challenging situations involving dynamic load profiles and disruptive conditions in order to assess the system dependability. An early-stage...
In recent years, cloud computing is establishing itself as the latest high-performance and high-throughput computing paradigm, and thus doing business in the cloud is becoming a reality. However, due to the dynamic nature of the cloud environment, the on-time completion of time-constrained business workflows is a big challenge. Workflow temporal verification as the major approach to monitor and control...
Today's complex integrated circuit designs increasingly rely on post-silicon validation to eliminate bugs that escape from pre-silicon verification. One effective silicon debug technique is to monitor and trace the behaviors of the circuit during its normal operation. However, due to the associated overhead, designers can only afford to trace a small number of signals in the design. Selecting which...
Trace-based debug solutions facilitate to eliminate design errors escaped from pre-silicon verification and have gained wide acceptance in the industry. Existing techniques typically trace the same set of signals throughout each debug run, which is not quite effective for catching design errors. In this work, we propose a multiplexed signal tracing strategy that is able to significantly increase debuggability...
