Adaptive Algorithms for Online Convex Optimization with Long-term Constraints
Rodolphe Jenatton, Jim Huang, Cédric Archambeau
We present an adaptive online gradient descent algorithm to solve online convex optimization problems with long-term constraints , which are constraints that need to be satisfied w…
Top-k Query Processing on Encrypted Databases with Strong Security Guarantees
Xianrui Meng, Haohan Zhu, George Kollios
Privacy concerns in outsourced cloud databases have become more and more important recently and many efficient and scalable query processing methods over encrypted data have been p…
Better Document-level Sentiment Analysis from RST Discourse Parsing
Parminder Bhatia, Yangfeng Ji, Jacob Eisenstein
Discourse structure is the hidden link between surface features and document-level properties, such as sentiment polarity. We show that the discourse analyses produced by Rhetorica…
Leveraging One-hop Information in Massive MIMO Full-Duplex Wireless Systems
Wenzhuo Ouyang, Jingwen Bai, Ashutosh Sabharwal
We consider a single-cell massive MIMO full-duplex wireless communication system, where the base-station (BS) is equipped with a large number of antennas. We consider the setup whe…
Newtonized Orthogonal Matching Pursuit: Frequency Estimation over the Continuum
Babak Mamandipoor, Dinesh Ramasamy, Upamanyu Madhow
We propose a fast sequential algorithm for the fundamental problem of estimating frequencies and amplitudes of a noisy mixture of sinusoids. The algorithm is a natural generalizati…
When Crowdsourcing Meets Mobile Sensing: A Social Network Perspective
Pin-Yu Chen, Shin-Ming Cheng, Pai-Shun Ting +2
Mobile sensing is an emerging technology that utilizes agent-participatory data for decision making or state estimation, including multimedia applications. This article investigate…
