On Incremental Sigma-Delta Modulation with Optimal Filtering
Sigma-Delta (Σ∆ ) incremental A/D converter optimal filter Σ∆ transfer function time-domain analysis
2015/8/12
The paper presents a quantization-theoretic framework for studying incremental Σ∆ data conversion systems. The framework makes it possible to efficiently compute the quantization intervals and h...
Slope One Predictors for Online Rating-Based Collaborative Filtering
Collaborative Filtering Recommender e-Commerce Data Mining Knowledge Discovery
2015/8/3
Rating-based collaborative filtering is the process of predicting how a user would rate a given item from other user ratings. We propose three related slope one schemes with predictors of the form f(x...
Improving Recommendation Quality by Merging Collaborative Filtering and Social Relationships
Collaborative Filtering Recommender Systems Social Networks Matrix Factorization
2015/7/21
Matrix Factorization techniques have been successfully applied to raise the quality of suggestions generated by Collaborative Filtering Systems (CFSs). Traditional CFSs based on Matrix Factorization o...

In recent years, a compelling need has arisen to understand the effects of distributed information structures on estimation and filtering. In this paper, a bibliographical review on distributed Kalman...
A Contextual Item-Based Collaborative Filtering Technology
Context Item-Based Collaborative Filtering
2013/1/28
This paper proposes a contextual item-based collaborative filtering technology, which is based on the traditional item-based collaborative filtering technology. In the process of the recommendation, u...
A novel and efficient algorithm for adaptive filtering: Artificial bee colony algorithm
Artificial bee colony Particle swarm optimization Differential evolution Adaptive filter design Noise cancellation
2011/3/22
The uni-modal error surfaces and intrinsic stable behaviors of adaptive finite impulse response (FIR) filters make gradient based algorithms very effective in the design of these filters. Gradient bas...
Enhanced Line-based Intra Prediction with Fixed Interpolation Filtering
Intra prediction image coding least square method
2013/7/24
In this paper, a novel intra prediction algorithm, named enhanced line-based intra prediction (ELIP), is proposed to improve the traditional intra prediction methods for image/intra-frame coding. Diff...
