pasta
Human Pasta age-shift classifier on within-sample rank-transformed expression. Its classifier score is rescaled to a relative age difference on a human-year axis; it is not an absolute chronological-age prediction.
Model weights retain the original authors' terms; the pyaging software license does not relicense them.
