Adaptive Superresolution in Deconvolution of Sparse Peaks
Alexandra Koulouri, Pia Heins, Martin Burger
The aim of this paper is to investigate superresolution in deconvolution driven by sparsity priors. The observed signal is a convolution of an original signal with a continuous ker…
Robust Vision Using Retro Reflective Markers for Remote Handling in ITER
Laura Goncalves Ribeiro, Olli J. Suominen, Sari Peltonen +2
ITER's working environment is characterized by extreme conditions, that deem maintenance and inspection tasks to be carried out through remote handling. 3D Node is a hardware/softw…
An Ensemble of Convolutional Neural Networks for Audio Classification
Loris Nanni, Gianluca Maguolo, Sheryl Brahnam +1
In this paper, ensembles of classifiers that exploit several data augmentation techniques and four signal representations for training Convolutional Neural Networks (CNNs) for audi…
Adaptive L2 Regularization in Person Re-Identification
Xingyang Ni, Liang Fang, Heikki Huttunen
We introduce an adaptive L2 regularization mechanism in the setting of person re-identification. In the literature, it is common practice to utilize hand-picked regularization fact…
Machine learning depinning of dislocation pileups
Mika Sarvilahti, Audun Skaugen, Lasse Laurson
We study a one-dimensional model of a dislocation pileup driven by an external stress and interacting with random quenched disorder, focusing on predictability of the plastic defor…
Backward phase-matched second-harmonic generation from stacked metasurfaces
Timo Stolt, Jeonghyun Kim, Sébastien Héron +6
We demonstrate phase-matched second-harmonic generation (SHG) from three-dimensional metamaterials consisting of stacked metasurfaces. To achieve phase matching, we utilize a novel…
