L-VAE: Variational Auto-Encoder with Learnable Beta for Disentangled Representation

Hazal Mogultay Ozcan, Sinan Kalkan, Fatos T. Yarman-Vural

In this paper, we propose a novel model called Learnable VAE (L-VAE), which learns a disentangled representation together with the hyperparameters of the cost function. L-VAE can b…
