 * [**Standard VAE Loss**](https://arxiv.org/abs/1312.6114): α=β=ɣ=1. Each term is computed exactly by a closed form solution (KL between the prior and the posterior). Tightest lower bound.
 * [**β-VAE<sub>H</sub>**](https://openreview.net/pdf?id=Sy2fzU9gl): α=β=ɣ>1. Each term is computed exactly by a closed form solution. Simply adds a hyper-parameter (β in the paper) before the KL.
 * [**β-VAE<sub>B</sub>**](https://arxiv.org/abs/1804.03599): α=β=ɣ>1. Same as **β-VAE<sub>H</sub>** but only penalizes the 3 terms once they deviate from a capacity C which increases during training.
-* [**FactorVAE**](https://arxiv.org/pdf/1802.05983.pdf): α=ɣ=1, β>1. Each term is computed exactly by a closed form solution. Simply adds a hyper-parameter (β in the paper) before the KL. Adds a weighted Total Correlation term to the standard VAE loss. The total correlation is estimated using a classifier and the density-ratio trick. Note that ɣ in their paper corresponds to β+1 in our framework.
-* [**β-TCVAE**](https://arxiv.org/pdf/1802.05983.pdf): α=ɣ=1 (although can be modified), β>1. Conceptually equivalent to FactorVAE, but each term is estimated separately using minibatch stratified sampling.
