# Popformer
An axial attention transformer for haplotype matrices, pre-trained with self-supervised masked haplotype reconstruction.
**Paper:** [Popformer: Learning general signatures of positive selection with a self-supervised transformer](https://www.biorxiv.org/content/10.64898/2026.03.06.710163v1)
## Model Description
Popformer is pre-trained on masked haplotype reconstruction and evaluated on:
- Natural selection detection
- Genotype imputation
- Population classification
## Usage
See the [repository README](https://github.com/zongleon/popformer) for full preprocessing and inference examples, including VCF/HDF5 input and genome-wide selection scans.
