$Λ$CDM and early dark energy in latent space: a data-driven parametrization of the CMB temperature power spectrum

Posted by dbos Tokyo

Kavli Affiliate: Eiichiro Komatsu | First 5 Authors: Davide Piras, Laura Herold, Luisa Lucie-Smith, Eiichiro Komatsu, | Summary: Finding the best parametrization for cosmological models in the absence of first-principle theories is an open question. We propose a data-driven parametrization of cosmological models given by the disentangled ‘latent’ representation of a variational autoencoder (VAE) trained […]

Rarely categorical, always high-dimensional: how the neural code changes along the cortical hierarchy

Posted by dbos Columbia

Kavli Affiliate: Stefano Fusi | Authors: Lorenzo Posani, Shuqi Wang, Samuel Muscinelli, Liam Paninski and Stefano Fusi | Summary: A long-standing debate in neuroscience concerns whether individual neurons are organized into functionally distinct populations that encode information differently (“categorical” representations [1–3]) and the implications for neural computation. Here, we systematically analyzed how cortical neurons encode […]

Imaging orbital Rashba induced charge transport anisotropy

Posted by dbos Delft

Kavli Affiliate: Andrea D. Caviglia | First 5 Authors: Eylon Persky, Xi Wang, Giacomo Sala, Thierry C. van Thiel, Edouard Lesne | Summary: Identifying orbital textures and their effects on the electronic properties of quantum materials is a critical element in developing orbitronic devices. However, orbital effects are often entangled with the spin degree of […]
