Covenant-72B: Pre-Training a 72B LLM with Trustless Peers Over-the-Internet

Joel Lidin, Amir Sarfi, Erfan Miahi +6

Recently, there has been increased interest in globally distributed training, which has the promise to both reduce training costs and democratize participation in building large-sc…

Heterogeneous Low-Bandwidth Pre-Training of LLMs

Yazan Obeidi, Amir Sarfi, Joel Lidin +2

Pre-training large language models (LLMs) increasingly requires distributed compute, yet bandwidth constraints make it difficult to scale beyond well-provisioned datacenters-especi…

Overcoming the Communication-Performance Tradeoff in LLM Pretraining

Amir Sarfi, Benjamin Thérien, Joel Lidin +1

Communication-efficient distributed training algorithms (e.g., DiLoCo) have received considerable interest due to their benefits for training large language models (LLMs) in bandwi…

Incentivizing Permissionless Distributed Learning of LLMs

Joel Lidin, Amir Sarfi, Evangelos Pappas +3

We describe an incentive system for distributed deep learning of foundational models where peers are rewarded for contributions. The incentive system, \textit{Gauntlet}, has been d…

Simulated Annealing in Early Layers Leads to Better Generalization

Amirmohammad Sarfi, Zahra Karimpour, Muawiz Chaudhary +4

Recently, a number of iterative learning methods have been introduced to improve generalization. These typically rely on training for longer periods of time in exchange for improve…

Diminishing the Effect of Adversarial Perturbations via Refining Feature Representation

Nader Asadi, AmirMohammad Sarfi, Mehrdad Hosseinzadeh +2

Deep neural networks are highly vulnerable to adversarial examples, which imposes severe security issues for these state-of-the-art models. Many defense methods have been proposed…
