| This repository contains a fastText pretraining data filter targeting the LAMBADA task, as discussed in the paper [Improving Pretraining Data Using Perplexity Correlations](https://arxiv.org/abs/2409.05816). This filter selects high-quality pretraining data based on correlations between LLM perplexity and downstream benchmark performance. | |
