Overview

• SampleMix is a new strategy for mixing pre-training data for language models
• Balances both data quality and diversity at the sample level
• Outperforms traditional dataset-level mixing approaches
• Uses a bivariate beta distribution to coordinate quality and diversity
• Achieves significant improvements on benchmark tasks
• Reduces training data requirements while maintaining performance

Plain English Explanation

When training large language models, researchers face a tricky problem: they need high-quality data that also represents diverse topics and writing styles. Think of it like cooking a great soup - you need both high-quality ingredients and a variety of flavors to make it tasty.
