Popular Vote (popV) model for automated cell type annotation of single-cell RNA-seq data. We provide here pretrained models
for plug-in use in your own analysis.
Follow our [tutorial](https://github.com/YosefLab/popV/blob/main/tabula_sapiens_tutorial.ipynb) to learn how to use the model for cell type annotation.
# Model description
Tabula Sapiens is a benchmark, first-draft human cell atlas of over 1.1M cells from 28 organs of 24 normal human subjects. This work is the product of the Tabula Sapiens Consortium. Taking the organs from the same individual controls for genetic background, age, environment, and epigenetic effects, and allows detailed analysis and comparison of cell types that are shared between tissues.

# Metrics
We provide here accuracies for each of the experts and the ensemble model. The validation set accuracies are
computed on a 10% random subset of the data that was not used for training.
