ControlVAE: Tuning, Analytical Properties, and Performance Analysis [article]

Huajie Shao, Zhisheng Xiao, Shuochao Yao, Aston Zhang, Shengzhong Liu, Tarek Abdelzaher
2020 arXiv   pre-print
This paper reviews the novel concept of controllable variational autoencoder (ControlVAE), discusses its parameter tuning to meet application needs, derives its key analytic properties, and offers useful  ...  In order to improve the ELBO over the regular VAE, we provide simplified theoretical analysis to inform setting the set point of KL-divergence for ControlVAE.  ...  -09-2-0053 and W911NF-17-2-0196.  ...

DynamicVAE: Decoupling Reconstruction Error and Disentangled Representation Learning [article]

Huajie Shao, Haohong Lin, Qinmin Yang, Shuochao Yao, Han Zhao, Tarek Abdelzaher
2020 arXiv   pre-print
To mitigate this problem, a ControlVAE has recently been developed that dynamically tunes the KL-divergence weight in an attempt to control the trade-off to more a favorable point.  ...  However, ControlVAE fails to eliminate the conflict between the need for a large β (for disentanglement) and the need for a small β.  ...  RESULTS AND ANALYSIS Dsprites Dataset: We first evaluate the performance of DynamicVAE on learning disentangled representations using dSprites.  ...
