Adjacent Leader Decentralized Stochastic Gradient Descent

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 […]

Symmetrically Threaded SQUIDs As Next Generation Kerr-cat Qubits

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 […]

Localizing Task Information for Improved Model Merging and Compression

Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Nikolaos Dimitriadis, Guillermo Ortiz-Jimenez, François Fleuret, Pascal Frossard | Summary: Model merging and task arithmetic have emerged as promising scalable approaches to merge multiple single-task checkpoints to one multi-task model, but their applicability is reduced by significant performance loss. Previous works have linked these drops […]
