Deep Optimizer States: Towards Scalable Training of Transformer Models Using Interleaved Offloading

Researchers introduce Deep Optimizer States, a technique that reduces GPU memory constraints during large language model training by dynamically offloading optimizer state between host and GPU memory during computation cycles. The method achieves 2.5× faster iterations compared to existing approaches by better managing the memory fluctuations inherent in transformer training pipelines.

Residual Koopman Spectral Profiling for Predicting and Preventing Transformer Training Instability

Researchers developed Residual Koopman Spectral Profiling (RKSP), a method that predicts transformer training instability from a single forward pass at initialization with 99.5% accuracy. The technique includes Koopman Spectral Shaping (KSS) which can prevent training divergence and enable 50-150% higher learning rates across various AI models including GPT-2 and LLaMA-2.

Optimizer-Induced Low-Dimensional Drift and Transverse Dynamics in Transformer Training

Researchers analyzed training trajectories in small transformer models, finding that parameter updates organize into a dominant drift direction with transverse dynamics. The study reveals that different optimizers (AdamW vs SGD) create substantially different trajectory geometries, with AdamW developing multi-dimensional structures while SGD produces more linear evolution.
