Meet, discuss, and segregate!

G Weisbuch, G Deffuant, F Amblard, JP Nadal - Complexity, 2002 - Wiley Online Library
We present a model of opinion dynamics in which agents adjust continuous opinions as a
result of random binary encounters whenever their difference in opinion is below a given …

Mutual information, Fisher information, and population coding

N Brunel, JP Nadal - Neural computation, 1998 - ieeexplore.ieee.org
In the context of parameter estimation and model selection, it is only quite recently that a
direct link between the Fisher information and information-theoretic quantities has been …

Nonlinear neurons in the low-noise limit: a factorial code maximizes information transfer

JP Nadal, N Parga - Network: Computation in neural systems, 1994 - Taylor & Francis
We investigate the consequences of maximizing information transfer in a simple neural
network (one input layer, one output layer), focusing on the case of nonlinear transfer functions. …

[HTML][HTML] Optimal information storage and the distribution of synaptic weights: perceptron versus Purkinje cell

N Brunel, V Hakim, P Isope, JP Nadal, B Barbour - Neuron, 2004 - cell.com
It is widely believed that synaptic modifications underlie learning and memory. However,
few studies have examined what can be deduced about the learning process from the …

Neural networks that learn temporal sequences by selection.

…, JP Changeux, JP Nadal - Proceedings of the …, 1987 - National Acad Sciences
A model for formal neural networks that learn temporal sequences by selection is proposed
on the basis of observations on the acquisition of song by birds, on sequence-detecting …

What can we learn from synaptic weight distributions?

B Barbour, N Brunel, V Hakim, JP Nadal - TRENDS in Neurosciences, 2007 - cell.com
Much research effort into synaptic plasticity has been motivated by the idea that modifications
of synaptic weights (or strengths or efficacies) underlie learning and memory. Here, we …

The acquisition of allophonic rules: Statistical learning with linguistic constraints

S Peperkamp, R Le Calvez, JP Nadal, E Dupoux - Cognition, 2006 - Elsevier
Phonological rules relate surface phonetic word forms to abstract underlying forms that are
stored in the lexicon. Infants must thus acquire these rules in order to infer the abstract …

[HTML][HTML] Epidemiological modelling of the 2005 French riots: a spreading wave and the role of contagion

…, MB Gordon, S Roché, N Rodriguez, JP Nadal - Scientific reports, 2018 - nature.com
As a large-scale instance of dramatic collective behaviour, the 2005 French riots started in a
poor suburb of Paris, then spread in all of France, lasting about three weeks. Remarkably, …

Heterogeneity and feedback in an agent-based market model

F Ghoulmie, R Cont, JP Nadal - Journal of Physics: condensed …, 2005 - iopscience.iop.org
We propose an agent-based model of a single-asset financial market, described in terms of
a small number of parameters, which generates price returns with statistical properties …

Cerebellar learning using perturbations

…, C Clopath, C Bimbard, J Ranft, A Blot, JP Nadal… - Elife, 2018 - elifesciences.org
10.7554/eLife.31599.001 The cerebellum aids the learning of fast, coordinated movements.
According to current consensus, erroneously active parallel fibre synapses are depressed …
