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 ...

Sensor Network Localization from Local Connectivity : Performance Analysis for the MDS-MAP Algorithm

Amin Karbasi, Andrea Montanari

Sensor localization from only connectivity information is a highly challenging problem. To this end, our result for the first time establishes an analytic bound on the performance of the popular MDS-MAP algorithm based on multidimensional scaling. For a ne ...

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 ...

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 ...

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 ...

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 ...

Segmenting memory colours

Sabine Süsstrunk, Francisco Estrada

Memory colours refer to the colour of specific image classes that have the essential attribute of being perceived in a consistent manner by human observers. In colour correction or rendering tasks, this consistency implies that they have to be faithfully r ...

A monotonic evaluation of lower bounds for inf-sup stability constants in the frame of reduced basis approximations

Jan Sickmann Hesthaven, Yvon Maday

For accurate a posteriori error analysis of the reduced basis method for coercive and non-coercive problems, a critical ingredient lies in the evaluation of a lower bound for the coercivity or inf-sup constant. In this short Note, we generalize and improve ...

Interactive spaces

Jeffrey Huang, Muriel Waldvogel

How do conceptions of space change with the infiltration of new elements of interactivity into our surroundings? What are the effects of digitalization on typological, tectonic and ornamental changes in contemporary architecture and cities? What are the ne ...
