Power-efficient dual-edge implicit pulse-triggered flip-flop with an embedded clock-gating scheme Article

Liang GENG,Ji-zhong SHEN,Cong-yuan XU

Frontiers of Information Technology & Electronic Engineering 2016, Volume 17, Issue 9,   Pages 962-972 doi: 10.1631/FITEE.1500293

Abstract: A novel dual-edge implicit pulse-triggered flip-flop with an embedded clock-gating scheme (DIFF-CGS)is proposed, which employs a transmission-gate-logic (TGL) based clock-gating scheme in the pulse generationThis scheme conditionally disables the inverter chain when the input data are kept unchanged, so redundantAlso, full-swing operations in both implicit pulse generation and the static latch improve the robustness

Frontiers of Information Technology & Electronic Engineering 2017, Volume 18, Issue 11,   Pages 1817-1827 doi: 10.1631/FITEE.1601468

Abstract: Implicit feedback, which indirectly reflects opinion through user behaviors, has gained increasing attentionA major way of exploiting implicit feedback is to treat the data as an indication of positive and negativeHowever, in real-world applications, there are usually various types of implicit feedback, which canbe referred to as heterogeneous implicit feedback.Existing methods cannot efficiently infer confidence levels from heterogeneous implicit feedback.

Preference transfer model in collaborative filtering for implicit data Project supported by Article

Bin JU,Yun-tao QIAN,Min-chao YE

Frontiers of Information Technology & Electronic Engineering 2016, Volume 17, Issue 6,   Pages 489-500 doi: 10.1631/FITEE.1500313

Abstract: Generally, predicting whether an item will be liked or disliked by active users, and how much an item will be liked, is a main task of collaborative filtering systems or recommender systems. Recently, predicting most likely bought items for a target user, which is a subproblem of the rank problem of collaborative filtering, became an important task in collaborative filtering. Traditionally, the prediction uses the user item co-occurrence data based on users’ buying behaviors. However, it is challenging to achieve good prediction performance using traditional methods based on single domain information due to the extreme sparsity of the buying matrix. In this paper, we propose a novel method called the preference transfer model for effective cross-domain collaborative filtering. Based on the preference transfer model, a common basis item-factor matrix and different user-factor matrices are factorized. Each user-factor matrix can be viewed as user preference in terms of browsing behavior or buying behavior. Then, two factor-user matrices can be used to construct a so-called ‘preference dictionary’ that can discover in advance the consistent preference of users, from their browsing behaviors to their buying behaviors. Experimental results demonstrate that the proposed preference transfer model outperforms the other methods on the Alibaba Tmall data set provided by the Alibaba Group.
