Addressing the problem of information overload, automatic multi-document summarization (MDS) has been widely utilized in the various real-world applications. Most of existing approaches adopt term-based representation for documents which limit the performance of MDS systems. In this paper, we proposed a novel unsupervised pattern-enhanced topic model (PETMSum) for the MDS task. PETMSum combining pattern...
This paper devises a transformation scheme to protect data privacy in the case that data have to be sent to the third party for the analysis purpose. Most conventional transformation schemes suffer from two limits, i.e., the algorithm dependency and the information loss. In this work, we propose a novel privacy preserving transformation scheme without these two limitations. The transformation is referred...
Jitter decomposition is important for identifying root sources of jitter. The limitations of the existing methods for jitter decomposition are discussed and a new approach with a combination of fast Fourier transform and time lag correlation is proposed. The new method reduces the number of equations and improves efficiency of jitter decomposition. Simulation is performed to validate the proposed...
A complete extraction technique of SiGe HBTs is developed to extract the base and collector current noises and their correlation. Unlike conventional methods, a four-port noise de- embedding technique is used to remove the influence of extrinsic elements. From the extraction results, we found that the base current noise and collector current noise can not be modeled well using 2qIB and 2qlc, respectively...
