Colloidal Suspensions can have Non-Zero Angles of Repose below the Minimal Value for Athermal Frictionless Particles
Jesús Fernández, Loïc Vanel, Antoine Bérut
We investigate the angle of repose of dense suspensions of colloidal silica particles ( to ) in water-filled microfluidic rotating drum experiments, to pr…
A Unified Perspective on Optimization in Machine Learning and Neuroscience: From Gradient Descent to Neural Adaptation
Jesús García Fernández, Nasir Ahmad, Marcel van Gerven
Iterative optimization is central to modern artificial intelligence (AI) and provides a crucial framework for understanding adaptive systems. This review provides a unified perspec…
Aging in the Flow Dynamics of Dense Suspensions of Contactless Microparticles
Jesús Fernández, Loïc Vanel, Antoine Bérut
This study demonstrates that the free-surface flow dynamics of dense piles of contactless silica microparticles depend on the resting period prior to flow. Microfluidic rotating dr…
Gradient-Free Training of Recurrent Neural Networks using Random Perturbations
Jesus Garcia Fernandez, Sander Keemink, Marcel van Gerven
Recurrent neural networks (RNNs) hold immense potential for computations due to their Turing completeness and sequential processing capabilities, yet existing methods for their tra…
Detecting the edges of galaxies with deep learning
Jesús Fernández, Fernando Buitrago, Benjamín Sahelices
Galaxy edges or truncations are low-surface-brightness (LSB) features located in the galaxy outskirts that delimit the distance up to where the gas density enables efficient star f…
