Mining Fix Patterns for FindBugs Violations
Kui Liu, Dongsun Kim, Tegawendé F. Bissyandé +2
In this paper, we first collect and track a large number of fixed and unfixed violations across revisions of software. The empirical analyses reveal that there are discrepancies in…
Together or Alone: The Price of Privacy in Collaborative Learning
Balazs Pejo, Qiang Tang, Gergely Biczok
Machine learning algorithms have reached mainstream status and are widely deployed in many applications. The accuracy of such algorithms depends significantly on the size of the un…
ANCHOR: logically-centralized security for Software-Defined Networks
Diego Kreutz, Jiangshan Yu, Fernando M. V. Ramos +1
While the centralization of SDN brought advantages such as a faster pace of innovation, it also disrupted some of the natural defenses of traditional architectures against differen…
Constrained Bayesian Active Learning of Interference Channels in Cognitive Radio Networks
Anestis Tsakmalis, Symeon Chatzinotas, Björn Ottersten
In this paper, a sequential probing method for interference constraint learning is proposed to allow a centralized Cognitive Radio Network (CRN) accessing the frequency band of a P…
Distributed Optimization for Coordinated Beamforming in Multi-Cell Multigroup Multicast Systems: Power Minimization and SINR Balancing
Oskari Tervo, Harri Pennanen, Dimitrios Christopoulos +2
This paper considers coordinated multicast beamforming in a multi-cell multigroup multiple-input single-output system. Each base station (BS) serves multiple groups of users by for…
Resource Optimization with Load Coupling in Multi-cell NOMA
Lei You, Di Yuan, Lei Lei +3
Optimizing non-orthogonal multiple access (NOMA) in multi-cell scenarios is much more challenging than the single-cell case because inter-cell interference must be considered. Most…
