Cortical-like dynamics in recurrent circuits optimized for sampling-based probabilistic inference

R Echeveste, L Aitchison, G Hennequin… - Nature …, 2020 - nature.com
Sensory cortices display a suite of ubiquitous dynamical features, such as ongoing noise
variability, transient overshoots and oscillations, that have so far escaped a common, principled …

Domain generalization via gradient surgery

L Mansilla, R Echeveste, DH Milone… - Proceedings of the …, 2021 - openaccess.thecvf.com
In real-life applications, machine learning models often face scenarios where there is a
change in data distribution between training and test domains. When the aim is to make …

[HTML][HTML] Addressing fairness in artificial intelligence for medical imaging

MA Ricci Lara, R Echeveste, E Ferrante - nature communications, 2022 - nature.com
A plethora of work has shown that AI systems can systematically and unfairly be biased against
certain populations in multiple scenarios. The field of medical imaging, where AI systems …

[HTML][HTML] Generating functionals for computational intelligence: the Fisher information as an objective function for self-limiting Hebbian learning rules

R Echeveste, C Gros - Frontiers in Robotics and AI, 2014 - frontiersin.org
Generating functionals may guide the evolution of a dynamical system and constitute a
possible route for handling the complexity of neural networks as relevant for computational …

[HTML][HTML] Energetic substrate availability regulates synchronous activity in an excitatory neural network

DS Tourigny, MKA Karim, R Echeveste, MRN Kotter… - PLoS …, 2019 - journals.plos.org

[HTML][HTML] The redemption of noise: Inference with neural populations

R Echeveste, M Lengyel - Trends in neurosciences, 2018 - cell.com
In 2006, Ma et al. presented an elegant theory for how populations of neurons might
represent uncertainty to perform Bayesian inference. Critically, according to this theory, neural …

[HTML][HTML] EI balance emerges naturally from continuous Hebbian learning in autonomous neural networks

P Trapp, R Echeveste, C Gros - Scientific reports, 2018 - nature.com
Spontaneous brain activity is characterized in part by a balanced asynchronous chaotic
state. Cortical recordings show that excitatory (E) and inhibitory (I) drivings in the EI balanced …

Two-trace model for spike-timing-dependent synaptic plasticity

R Echeveste, C Gros - Neural computation, 2015 - direct.mit.edu
We present an effective model for timing-dependent synaptic plasticity (STDP) in terms of
two interacting traces, corresponding to the fraction of activated NMDA receptors and the …

Bridging physiological and perceptual views of autism by means of sampling-based Bayesian inference

R Echeveste, E Ferrante, DH Milone… - Network …, 2022 - direct.mit.edu
