A Subband Adaptive Iterative Shrinkage/Thresholding Algorithm

Ilker Bayram

We investigate a subband adaptive version of the popular iterative shrinkage/thresholding algorithm that takes different update steps and thresholds for each subband. In particular, we provide a condition that ensures convergence and discuss why making the ...

Nonlinear Average Consensus

Martin Hasler, Leonidas Georgopoulos

We present an algorithm for nonlinear consensus in complex networks. Our motivation draws from analysis on the algorithm based on a weighted linear update protocol. Comparison of the asymptotic with early convergence rate encourages an alternative algorith ...

Diffusion least-mean squares with adaptive combiners

Ali H. Sayed

This paper presents an efficient adaptive combination strategy for diffusion algorithms over adaptive networks in order to improve the robustness against the spatial variation of SNR over the network. The diffusion least-mean square (LMS) algorithm with th ...

Testing a reliable in-vehicle navigation algorithm in the field

The results of a field experiment carried out to assess the accuracy and efficiency of a new in-vehicle navigation algorithm, whose aim is to incorporate and consider travel time reliability and route the guided vehicle along uncongested roads, in the abse ...

A Simple Alternative Derivation of the Expectation Correction Algorithm

Bertrand Mesot

The switching linear dynamical system (SLDS) is a popular model in time-series analysis. However, the complexity of inferring the state of the latent variables scales exponentially with the length of the time-series, resulting in many approximation strateg ...

Multimodal Speaker Localization from Omnidirectional Videos

Jean-Philippe Thiran, Mihai Gurban, Pascal Reuse

The use of omnidirectional cameras for videoconferencing promises to simplify the hardware setup necessary for large groups of participants. We investigate the use of a multimodal speaker detection algorithm on audio-visual sequences captured with such a c ...

Applying combined field integral equation technique to analyze quasi-waveguide structures

Juan Ramon Mosig, Michael Mattes, Laleh Golestanirad

In this paper a detailed mathematical procedure is described to evaluate modal scattering parameters conventionally defined in planar multilayered structures excited by wave ports. Combined Field Integral Equation technique is implemented and solved using ...

Self-organization in bird flight formations using diffusion adaptation

Ali H. Sayed

Flocks of birds self-organize into V-formations when they need to travel long distances. It has been shown that this formation allows the birds to save energy, by taking advantage of the upwash generated by the neighboring birds. In this work we use a simp ...

A Scalable, Sound, Eventually-Complete Algorithm for Deadlock Immunity

George Candea, Horatiu Jula

We introduce the concept of deadlock immunity—a program's ability to avoid all deadlocks that match patterns of deadlocks experienced in the past. We present here an algorithm for enabling large software systems to automatically acquire such immunity witho ...
