What is preselect-fasttext-classifier?
The preselect-fasttext-classifier is a specialized binary classification model designed to identify and filter high-quality data in pretraining corpora. This model serves as the backbone for creating the PreSelect-100B dataset, implementing a selective approach with a 10% threshold for data quality assessment. The classifier leverages FastText architecture to make efficient decisions about text quality, making it particularly valuable for large-scale data curation tasks.
Implementation Details
The model implements a straightforward yet effective approach to data filtering using FastText architecture. It can be easily integrated into existing data processing pipelines through Python, supporting both JSON and Parquet file formats. The implementation includes built-in support for parallel processing with customizable task distribution.
