Researchers have introduced FARO, a novel optimization framework designed to improve the training of large language models. FARO adapts the optimization process by treating parameter blocks as the fundamental unit, dynamically assigning geometries based on their counterfactual return. This approach reallocates the update budget using a risk-parity principle, similar to portfolio theory. In experiments with a GPT-style model on the FineWeb dataset, FARO's adaptive arm matched the performance of existing hand-designed methods, while its ERC variant achieved a modest but consistent improvement in loss reduction across multiple seeds.
