Efficient Long-Horizon Learning for Learned Optimization

Xiaolong Huang, Benjamin Thérien, James Harrison +1

Learned optimization aims to improve upon hand-designed optimizers (e.g., Adam and Muon) by meta-learning small neural network optimizers over a distribution of tasks. While recent…

Stabilizing Native Low-Rank LLM Pretraining

Paul Janson, Edouard Oyallon, Eugene Belilovsky

The paper presents a method to train large language models from scratch using only low‑rank factorized weights by introducing Spectron, a spectral renormalization and orthogonaliza…

Can Model Merging Improve Aggregation in DiLoCo?

Stefan Horoi, Benjamin Thérien, Guy Wolf +1

Model merging techniques, which aggregate independently finetuned models into one to combine their capabilities, have become a topic of significant interest in recent years, with a…

Stabilizing Black-Box Prompt Optimization with Textual Regularization and Signal Aggregation

MohammadReza Davari, Utkarsh Garg, Weixin Cai +1

An increasing number of NLP applications interact with large language models (LLMs) through black-box APIs, making prompt engineering critical for controlling model behavior. Recen…

From Memorization to Parameter Interference: How Overtraining Experts Harms Model Merging

Stefan Horoi, Guy Wolf, Eugene Belilovsky +1

Modern deep learning is increasingly characterized by the use of open-weight foundation models that can be fine-tuned on specialized datasets. This has led to a proliferation of ex…

Unifying Local Communications and Local Updates for LLM Pretraining

Pietro Cagnasso, Eugene Belilovsky, Edouard Oyallon

Communication-efficient pre-training of LLMs is increasingly important as training draws on compute distributed across clusters, data centers, and lower-bandwidth links. Many pract…
