This paper describes design techniques of enabling energy-efficient 3-tap decision feedback equalizer (DFE) to operate adaptively at 40Gb/s in 65nm CMOS technology. First, we propose a closed-loop architecture utilizing three techniques to achieve the 1st tap stage design, namely a merged latch and summer, reduced latch gain, and a dynamic latch design. Then, we suggest to merge the feedback MUX with...
To efficiently deal with the curse of dimensionality in the content-based image retrieval (CBIR) system, a novel image retrieval algorithm is proposed by combination of local discriminant embedding (LDE) and least square SVM (LS-SVM) in this paper. LDE aims to achieve good discriminating performance by integrating the local geometrical structure and class relations between image data. LS-SVM classifier...
To efficiently deal with spam mail filtering problem, a novel spam filtering algorithm based on locality pursuit projection (LPP) and least square version of SVM(LS-SVM) is proposed in this paper. The mail message features are first extracted by the LPP algorithm, then the LS-SVM classifier is used to classify mails into spam and legitimate. Experimental results demonstrate that the proposed algorithm...
