Neuromorphic Computing Using Non-Volatile Memory
Seyoung Kim, Yusuf Leblebici, Irem Boybat Kara, Alessandro Fumarola, Abu Sebastian, Severin Sidler
Dense crossbar arrays of non-volatile memory (NVM) devices represent one possible path for implementing massively-parallel and highly energy-efficient neuromorphic computing systems. We first review recent advances in the application of NVM devices to thre ...
Taylor & Francis Ltd2016Accelerated Spectral Clustering Using Graph Filtering of Random Signals
Pierre Vandergheynst, Rémi Gribonval, Gilles Puy, Nicolas Tremblay
We build upon recent advances in graph signal processing to propose a faster spectral clustering algorithm. Indeed, classical spectral clustering is based on the computation of the first eigenvectors of the similarity matrix' Laplacian, whose computati ...
Ieee2016Reduced Basis Methods: From Low-Rank Matrices To Low-Rank Tensors
Daniel Kressner, Jonas Ballani
We propose a novel combination of the reduced basis method with low-rank tensor techniques for the efficient solution of parameter-dependent linear systems in the case of several parameters. This combination, called rbTensor, consists of three ingredients. ...
Siam Publications2016MATHICSE Technical Report : A fast gradient method for nonnegative sparse regression with self dictionary
Nonnegative matrix factorization (NMF) can be computed efficiently under the separability assumption, which asserts that all the columns of the input data matrix belong to the convex cone generated by only a few of its columns. The provably most robust met ...
MATHICSE2016Near-Field Integration of a Si3N4 Nanobeam and a SiO2 Microcavity for Heisenberg-Limited Displacement Sensing
Tobias Kippenberg, Dalziel Joseph Wilson, Ryan Daniel Schilling, Vivishek Sudhir, Amir Hossein Ghadimi
A single-chip radio-frequency optomechanical system, consisting of a Si3N4 nanobeam in the evanescent near-field of a SiO2 optical microdisk resonator realizes displacement imprecision >30dB below the standard quantum limit at room-temperature. ...
Ieee2016Effect of hydrostatic pressure on flow and deformation in highly reinforced particulate composites
Andreas Mortensen, Ludger Weber, Maria Gabriella Tarantino
Infiltrated particle reinforced composites combine a dense matrix with particles that are in mutual contact and can therefore transfer compressive stress directly from one particle to the next. As a result, these composites may combine characteristics of t ...
Elsevier2016Anomalous thermal decoherence in a quantum magnet measured with neutron spin echo spectroscopy
The effect of temperature dependent asymmetric line broadening is investigated in Cu(NO3)(2)center dot 2.5D(2)O, a model material for a one-dimensional bond alternating Heisenberg chain, using the high resolution neutron-resonance spin echo (NRSE) techniqu ...
Amer Physical Soc2016Experimental method for the evaluation of the dynamic transfer matrix using pressure transducers
François Avellan, Andres Müller, Keita Yamamoto
This paper introduces an experimental method for the evaluation of dynamic transfer matrices using only pressure transducers. The discharge fluctuations are evaluated from the fluctuation of the pressure difference at different streamwise locations. The tr ...
Taylor & Francis Ltd2015MATHICSE Technical Report : Riemannian optimization for high-dimensional tensor completion
Michael Maximilian Steinlechner
Tensor completion aims to reconstruct a high-dimensional data set with a large fraction of missing entries. The assumption of low-rank structure in the underlying original data allows us to cast the completion problem into an optimization problem restricte ...
MATHICSE2015Unlabeled Sensing
Like other data sensing problems, in unlabeled sensing, the target is to solve the equation y = Φx by finding vector x given a set of sample values in vector y as well as the matrix Φ. However, the main challenge in unlabeled sensing is that the correct or ...
