Evaluating Sample Utility for Efficient Data Selection by Mimicking Model Weights

Researchers introduce the Mimic Score, a geometry-based metric for evaluating data quality in large datasets by measuring gradient alignment with pre-trained models. The proposed Grad-Mimic framework enables efficient data selection, reducing training steps for CLIP models by 20.7% and filtering datasets without expensive computations or validation sets.

GAC: Stabilizing Asynchronous RL Training for LLMs via Gradient Alignment Control

Researchers propose GAC (Gradient Alignment Control), a new method to stabilize asynchronous reinforcement learning training for large language models. The technique addresses training instability issues that arise when scaling RL to modern AI workloads by regulating gradient alignment and preventing overshooting.
