The Red Queen Gödel Machine: Co-Evolving Agents and Their Evaluators

Alex Iacob, Andrej Jovanović, William F. Shen +10

Self-improving agents are state-of-the-art (SOTA) on agentic coding benchmarks and have recently been extended to general domains. However, their search methods generally assume a…

FoMoE: Breaking the Full-Replica Barrier with a Federation of MoEs

Lorenzo Sani, Zeyu Cao, Meghdad Kurmanji +5

Pre-training Large Language Models (LLMs) typically demands large-scale infrastructure with tightly coupled hardware accelerators. Mixture-of-Experts (MoEs) architectures partially…

PreLort: Prefix-Nested LoRA for Federated Fine-Tuning under Rank Heterogeneity

Muhammad Waseem, Nurbek Tastan, Andrej Jovanovic +4

Federated fine-tuning of large language models using parameter-efficient methods such as LoRA enables privacy-preserving adaptation of foundation models. Heterogeneous hardware res…

MT-DAO: Multi-Timescale Distributed Adaptive Optimizers with Local Updates

Alex Iacob, Andrej Jovanovic, Mher Safaryan +6

Training large models with distributed data parallelism (DDP) requires frequent communication of gradients across workers, which can saturate bandwidth. Infrequent communication st…

DES-LOC: Desynced Low Communication Adaptive Optimizers for Training Foundation Models

Alex Iacob, Lorenzo Sani, Mher Safaryan +8

Scaling foundation model training with Distributed Data Parallel (DDP) methods is bandwidth-limited. Existing infrequent communication methods like Local SGD were designed to synch…
