# VAE posterior log-variance mathematical notation

VAE posterior log-variance is a recurring research-paper notation family. Parameterizes positive latent variances in an unconstrained logarithmic space…

## Public overview

VAE posterior log-variance is a recurring research-paper notation family. Parameterizes positive latent variances in an unconstrained logarithmic space predicted by a variational encoder.

VAE posterior log-variance: Parameterizes positive latent variances in an unconstrained logarithmic space predicted by a variational encoder. Example: Convert each predicted log-variance into a positive standard deviation.
