Driven criticality links universal computation and optimal representations
Adrián Roig, Miguel A. Muñoz, Guillermo B. Morales
Near-critical dynamics are often linked to enhanced computation, but the underlying mechanism remains unclear. We address this question in reservoir computing, where a fixed recurr…
Robust Scaling in Human Brain Dynamics Despite Latent Variables and Limited Sampling Distortions
Rubén Calvo, Carles Martorell, Adrián Roig +1
The idea that information-processing systems operate near criticality to enhance computational performance is supported by scaling signatures in brain activity. However, external s…
Representational Drift and Learning-Induced Stabilization in the Olfactory Cortex
Guillermo B. Morales, Miguel A. Muñoz, Yuhai Tu
The brain encodes external stimuli through patterns of neural activity, forming internal representations of the world. Recent experiments show that neural representations for a giv…
Networks with many structural scales: a Renormalization Group perspective
Anna Poggialini, Pablo Villegas, Miguel A. Muñoz +1
Scale invariance profoundly influences the dynamics and structure of complex systems, spanning from critical phenomena to network architecture. Here, we propose a precise definitio…
