For artists and poets, the ‘Roman walk’ was a sublime experience, where the emulation of ancient splendour produced an inner catharsis. Meanwhile, for architects it became fertile territory for the imagination, where the accumulation of layers and objects ...
Silvana2023Byzantine Machine Learning Made Easy By Resilient Averaging of Momentums
Rachid Guerraoui, Nirupam Gupta, John Stephan, Sadegh Farhadkhani, Rafaël Benjamin Pinot
Byzantine resilience emerged as a prominent topic within the distributed machine learning community. Essentially, the goal is to enhance distributed optimization algorithms, such as distributed SGD, in a way that guarantees convergence despite the presence ...
PMLR2022Collaborative Learning in the Jungle (Decentralized, Byzantine, Heterogeneous, Asynchronous and Nonconvex Learning)
Rachid Guerraoui, Sadegh Farhadkhani, El Mahdi El Mhamdi, Le Nguyen Hoang, Sébastien Louis Alexandre Rouault, Arsany Hany Abdelmessih Guirguis
We study Byzantine collaborative learning, where n nodes seek to collectively learn from each others' local data. The data distribution may vary from one node to another. No node is trusted, and f < n nodes can behave arbitrarily. We prove that collaborati ...
2021Natural and anthropogenic variations in methane sources during the past two millennia
Jed Oliver Kaplan, Kristen Marie Krumhardt
Methane is an important greenhouse gas that is emitted from multiple natural and anthropogenic sources. Atmospheric methane concentrations have varied on a number of time scales in the past, but what has caused these variations is not always well understoo ...
