Euclidean Distance Matrices: Essential Theory, Algorithms and Applications

Martin Vetterli, Ivan Dokmanic, Juri Ranieri, Reza Parhizkar

Euclidean distance matrices (EDMs) are matrices of the squared distances between points. The definition is deceivingly simple; thanks to their many useful properties, they have found applications in psychometrics, crystallography, machine learning, wireles ...

Spatial Sound Localization via Multipath Euclidean Distance Matrix Recovery

Hervé Bourlard, Philip Neil Garner, Afsaneh Asaei, Mohammadjavad Taghizadeh, Saeid Haghighatshoar

A novel localization approach is proposed in order to find the position of an individual source using recordings of a single microphone in a reverberant enclosure. The multipath propagation is modeled by multiple virtual microphones as images of the actual ...

Preconditioned Spectral Descent for Deep Learning

Volkan Cevher, Ya-Ping Hsieh, Edo Collins

Deep learning presents notorious computational challenges. These challenges in- clude, but are not limited to, the non-convexity of learning objectives and estimat- ing the quantities needed for optimization algorithms, such as gradients. While we do not a ...

Motion of an elastic capsule in a constricted microchannel

Lailai Zhu, Cecilia Rorai

We study the motion of an elastic capsule through a microchannel characterized by a localized constriction. We consider a capsule with a stress-free spherical shape and impose its steady-state configuration in an infinitely long straight channel as the ini ...

Excitation of Sodium Atoms Attached to Helium Nanodroplets: The 3p

Marcel Drabbels, Evgeniy Loginov, Alberto Hernando de Castro

The dynamics of Na atoms on the surface of helium nanodroplets following excitation via the 3p

Enabling Speech Applications using Ad Hoc Microphone Arrays

Mohammadjavad Taghizadeh

Microphone arrays are central players in hands-free speech interface applications. The main duty of a microphone array is capturing distant-talking speech with high quality. A microphone array can acquire the desired speech signals selectively by leading t ...

DexROV: Dexterous Undersea Inspection and Maintenance in Presence of Communication Latencies

Sylvain Calinon, Ajay Kumar Tanwani

Underwater inspection and maintenance (e.g. in the oil & gas industry) are demanding and costly activities for which ROV based setups are often deployed in addition or in substitution to deep divers - contributing to operations risks and costs cutting. How ...

Euclidean distance versus travel time in business location: A probabilistic mixture of hurdle-Poisson models

Matthieu Marie Cochon de Lapparent

While the question of the specification of spatial weight matrix is now largely discussed in the spatial econometrics literature, the definition of distance has attracted less attention. The choice of the distance measure is often glossed over, with the ul ...

Approximate Matrix Multiplication with Application to Linear Embeddings

Michail Vlachos, Anastasios Kyrillidis

In this paper, we study the problem of approximately computing the product of two real matrices. In particular, we analyze a dimensionality-reduction-based approximation algorithm due to Sarlos [1], introducing the notion of nuclear rank as the ratio of th ...

Theoretical Analysis of Euclidean Distance Matrix Completion for Ad hoc Microphone Array Calibration

Mohammadjavad Taghizadeh

We consider the problem of ad~hoc microphone array calibration where the distance matrix consisted of all microphones pairwise distances have entries missing corresponding to distances greater than

d_{\text{max}}

. Furthermore, the known entries are noisy ...
