A Diversity Diet for a Healthier Model: A Case Study of French ModernBERT

Read the original on arXiv Computation and Language →

The study explores how diversity-driven sampling can reduce the size of pre‑training datasets for ModernBERT models in French while preserving performance. By comparing several diversity algorithms, the authors pre‑train models on a fraction of the data and evaluate them on multiple French benchmarks. Results show that both random and diversity sampling can cut dataset size by up to 94% and training time by up to 73%, with diversity sampling sometimes improving model quality by up to 10 points.

Frequency Matters: Fast Model-Agnostic Data Curation for Pruning and Quantization

The paper introduces ZipCal, a model‑agnostic data curation method that selects calibration data for post‑training compression of large language models by maximizing lexical diversity using Zipfian power laws. ZipCal outperforms uniform random sampling on pruning benchmarks and matches a state‑of‑the‑art perplexity‑based approach while being roughly 240× faster due to its linear complexity. The authors provide code and experiments at their GitHub repository.

Chopthin-Consensus Power Sampling: A Diversity-Preserving Approach to LLM Decoding

Chopthin-Consensus Power Sampling (CCPS) is a new inference-time decoding method for large language models that uses the Chopthin resampler to preserve diversity among particle trajectories. By enforcing an upper bound on weight ratios instead of equal-weight resampling, CCPS maintains a richer set of distinct reasoning paths and guarantees a lower bound on effective sample size. Coupled with a semantic-majority selection mechanism, CCPS achieves higher oracle coverage and matches or surpasses baseline accuracy on multiple reasoning benchmarks.
