This fastText model is a filter for selecting high-quality pretraining data, as described in [Improving Pretraining Data Using Perplexity Correlations](https://arxiv.org/abs/2409.05816). It targets the LAMBADA IT task.
The model uses perplexity correlations to identify text segments highly correlated with strong performance on downstream benchmarks. It doesn't perform text classification directly; instead, it outputs a score indicating the suitability of a text segment for pretraining.
For complete usage instructions and the theoretical background, please refer to the [project's GitHub repository](https://github.com/TristanThrush/perplexity-correlations). |
