Trainable hardware for dynamical computing using error backpropagation through physical media

Article, Preprint English OPEN

Hermans, Michiel; Burm, Michaël; Van Vaerenbergh, Thomas; Dambre, Joni; Bienstman, Peter;

(2015)

Publisher: Nature Pub. Group

Machine learning algorithms, and more in particular neural networks, arguably experience a revolution in terms of performance. Currently, the best systems we have for speech recognition, computer vision and similar problems are based on neural networks, trained using th...

The Effects of Context and Attention on Spiking Activity in Human Early Visual Cortex

Article English OPEN

Self, Matthew W; Peters, Judith C; Possel, Jessy K; Reithler, Joel; Goebel, Rainer; Ris, Peterjan; Jeurissen, Danique; Reddy, Leila; Claus, Steven; Baayen, Johannes C; Roelfsema, Pieter R;

Here we report the first quantitative analysis of spiking activity in human early visual cortex. We recorded multi-unit activity from two electrodes in area V2/V3 of a human patient implanted with depth electrodes as part of her treatment for epilepsy. We observed well-...

Here we describe a multi-compartment neuron circuit based on the Adaptive-Exponential I&F (AdEx) model, developed for the second-generation BrainScaleS hardware. Based on an existing modular Leaky Integrate-and-Fire (LIF) architecture designed in 65 nm CMOS, the circuit...

Plasticity in memristive devices for spiking neural networks

Article English OPEN

SaÏghi, S.; Mayr, C.G.; Serrano-Gotarredona, T.; Schmidt, H.; Lecerf, G.; Tomas, J.; Grollier, J.; Boyn, S.; Vincent, A.F.; Querlioz, D.; La Barbera, S.; Alibart, F.; Vuillaume, D.; Bichler, O.; Gamrat, C.; ...

Despite the constant improvement of algorithms for automated brain tissue classification, the accurate delineation of subcortical structures using magnetic resonance images (MRI) data remains challenging. The main difficulties arise from the low gray-white matter contra...

Putting Actions in Context: Visual Action Adaptation Aftereffects Are Modulated by Social Contexts

Article English OPEN

de la Rosa, S.; Streuber, S.; Giese, M.; Bülthoff, H.; Curio, C.;

(2014)

Publisher: Public Library of Science

The social context in which an action is embedded provides important information for the interpretation of an action. Is this social context integrated during the visual recognition of an action? We used a behavioural visual adaptation paradigm to address this question ...

Neural Networks as Sources of uncorrelated Noise for functional neural Systems

Conference object English CLOSED

Jordan, Jakob; Petrovici, Mihai; Tetzlaff, Tom; Pfeil, Thomas; Breitwieser, Oliver; Bytschok, Ilya; Bill, Johannes; Gruebl, Andreas; Schemmel, Johannes; Meier, Karlheinz; Diesmann, Markus;

Neural-network models of brain function often rely on the presence of noise [1,2]. Yet thebiological origin of this noise remains unclear. In computer simulations and in neuromorphichardware [3,4], the number of noise sources (random-number generators) is limited. In co...

Automatic target validation based on neuroscientific literature mining for tractography

Article English OPEN

Vasques, Xavier; Richardet, Renaud; Hill, Sean L.; Slater, David; Chappelier, Jean-Cedric; Pralong, Etienne; Bloch, Jocelyne; Draganski, Bogdan; Cif, Laura;

(2015)

Publisher: Frontiers Research Foundation (Lausanne)

Project: EC | HBP (604102)

Target identification for tractography studies requires solid anatomical knowledge validated by an extensive literature review across species for each seed structure to be studied. Manual literature review to identify targets for a given seed region is tedious and poten...
