VAE by Label Relevant/Irrelevant Dimensions Zhilin Zheng Li Sun Shanghai Key Laboratory of Multidimensional Information Processing, East China Normal University 51171214020@stu.ecnu.edu.cn sunli@ee.ecnu.edu.cn Abstract VAE requires the standard Gaussian distribution as a...
(c) is the 3D visualization, it shows that the effects of class proportions on the magnitudes of the modes. 3.2 How do we train an LVM? 3.2.1 Traditional Method The goal is still to fit the marginal distribution p(x) However, this optimization objective is more difficult than regular log...
Here we will scan the latent plane, sampling latent points at regular intervals and generating the corresponding digit for each of these points. This gives us a visualization of the latent manifold that “generates” the MNIST digits. # Display a 2D manifold of the digits n = 15 # figure w...
model achieves better objective scores than the DAR, has a smaller memory footprint and is computationally faster. Visualization of the latent codes for phones and moras reveals that each latent code represents an $F_0$ shape for a linguistic unit....
Visualization of learning dynamics in the latent space To visualize the learning processes on an illustrative problem, let’s considera synthetic dataset(opens in new tab)consisting of 10 different sequences, as well as a VAE model with a 2-dimensional latent space,...

Conditional VAEs are excellent choices for visualization and image generation, in which specific objects or scenes are needed, along with image-to-image translation -- e.g., transforming black-and-white images into color images or converting sketches into photos. They're also good for text ...
During model training we track how well it reconstructs images from their latent representations. The images used for reconstruction are drawn from the validation set. A visualization of the reconstructed images for all training epochs is shown below. We can see that after a few epochs the model...
Additionally, the proposed approach improves the current state-of-the-art for classifying cardiovascular images and allows the visualization of the most discriminative attributes by projecting the trained latent space. Future work will be focused on improving the generalization of the trained Attri-VAE ...
