Kavli Affiliate: Jing Wang | First 5 Authors: Haoze He, Jing Wang, Anna Choromanska, , | Summary: This work focuses on the decentralized deep learning optimization framework. We propose Adjacent Leader Decentralized Gradient Descent (AL-DSGD), for improving final model performance, accelerating convergence, and reducing the communication overhead of decentralized deep learning optimizers. AL-DSGD relies on […]
Kavli Affiliate: Ke Wang | First 5 Authors: Bibek Bhandari, Irwin Huang, Ahmed Hajr, Kagan Yanik, Bingcheng Qing | Summary: Kerr-cat qubits are bosonic qubits with autonomous protection against bit-flips. They have been studied widely using driven Superconducting Nonlinear Asymmetric Inductive eLement (SNAIL) oscillators. We theoretically investigate an alternate circuit for the Kerr-cat qubit, namely […]

Grimm, Sarah E. Plutkis, Katie L. Holland, Liam Paninski, Luke Lavis and Adam Ezra Cohen | Summary: Dendrites on neurons support nonlinear electrical excitations, but the computational […]
Kavli Affiliate: Erin Kara | First 5 Authors: Yuhan Yao, Muryel Guolo, Francesco Tombesi, Ruancun Li, Suvi Gezari | Summary: We present the tidal disruption event (TDE) AT2022lri, hosted in a nearby ($approx!144$ Mpc) quiescent galaxy with a low-mass massive black hole ($10^4,M_odot < M_{rm BH} < 10^6,M_odot$). AT2022lri belongs to the TDE-H+He subtype. More […]
Kavli Affiliate: Naoyuki Tamura | First 5 Authors: Irumi Sugimori, Katsumi Inoue, Hidetomo Nabeshima, Torsten Schaub, Takehide Soh | Summary: We propose Large Neighborhood Prioritized Search (LNPS) for solving combinatorial optimization problems in Answer Set Programming (ASP). LNPS is a metaheuristic that starts with an initial solution and then iteratively tries to find better solutions […]
