A Post-Processing-Based Fair Federated Learning Framework

Kavli Affiliate: Yi Zhou | First 5 Authors: Yi Zhou, Naman Goel, , , | Summary: Federated Learning (FL) allows collaborative model training among distributed parties without pooling local datasets at a central server. However, the distributed nature of FL poses challenges in training fair federated learning models. The existing techniques are often limited in […]

The geometry of the neural state space of decisions

Kavli Affiliate: Kenneth Miller | Authors: Mauro M. Monsalve-Mercado and Kenneth D Miller | Summary: How do populations of neurons collectively encode and process information during cognitive tasks? We analyze high-yield population recordings from the macaque lateral intraparietal area (LIP) during a reaction-time random-dot-motion direction-discrimination task. We find that the trajectories of neural population activity […]

Three-dimensional core-collapse supernova models with phenomenological treatment of neutrino flavor conversions

Kavli Affiliate: Shunsaku Horiuchi | First 5 Authors: Kanji Mori, Tomoya Takiwaki, Kei Kotake, Shunsaku Horiuchi, | Summary: We perform three-dimensional supernova simulations with a phenomenological treatment of neutrino flavor conversions. We show that the explosion energy can increase to as high as ~10^51 erg depending on the critical density for the onset of flavor […]

Atomic collapse in gapped graphene: lattice and valley effects

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Xiaotai Wu, Wen-Sheng Zhao, Yuhua Cheng, Yue Hu | Summary: We study the atomic collapse phenomenon in $K$ and $K’$ valley of gapped graphene. Bound states induced by Coulomb impurity in the gap turn into atomic collapse resonances as the charge increases beyond the supercritical […]
