 # AgeSynth – Age Scalar ⇄ Chronological Age Regression Models
 
-This directory stores regression models that convert the **StyleGAN age scalar** obtained when traversing the AgeSynth age-direction in StyleGAN2’s $\mathcal{W}$ space into an estimated chronological age (and vice-versa), depending on the original subject's age. The mappings were produced by fitting linear and polynomial regressions on a curated subset of images from the **UTKFace** dataset, after projecting each image into StyleGAN2 and measuring the scalar value along the learned age direction.
