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...
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...
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...

2010/10/12
With the evolution of the Internet and e-commerce, collaborative filtering (CF) and privacy-preserving collaborative filtering (PPCF) have become popular. The goal in CF is to generate predictions wit...
Tree Automata for Schema-level Filtering of XML Associations
Access control association object flexible security granularity XML security tree automata
2014/3/12
In this paper we present query-filtering techniques based on bottom-up tree automata for XML access control. In our authorization model (RXACL), RDF statements are used to represent security objects a...
