arXiv:2607.01104v1 Announce Type: cross Abstract: In Large Language Model (LLM) training, data mixing plays a pivotal role in determining model performance. Recent methods optimize mixture weights via proxy models, but they rely on the assumption of static data distributions. As a result, when the underlying data pool shifts, these methods require costly retraining from scratch. This limitation restricts their ability to scale seamlessly from small settings to larger data pools and model sizes. In this paper, we propose CausalMix to address this limitation by casting data mixture optimization
The increasing scale and complexity of LLMs necessitate more efficient and adaptable training methodologies to overcome current limitations in data distribution shifts.
Optimized data mixing that flexibly scales with LLM size and data pools directly impacts the cost, performance, and accessibility of advanced AI models.
Traditional data mixture methods requiring costly retraining are challenged by a new approach that assumes dynamic data distributions, enabling more robust and scalable LLM development.
