Existing works based on MoE or PoE have shown notable improvement on data generation, while new challenges such as high training cost, overconfident experts, and encoding modal-specific features also emerge. What makes variational encoders different is that they try to describe observations in the latent space in probabilistic terms. Kingma, D. P., & Welling, M. (2014).

These two kinds of autoencoders are trained alternately by adopting variational expectation maximization algorithm. The proposed model uses stochastic gradient variational Bayes to estimate intractable posteriors and expectationmaximization-style estimators to learn model parameters.

Evidence Brief: The Effectiveness Of Mandatory Computer-Based Trainings On Government Ethics, Workplace Harassment, Or Privacy And Information Security-Related Topics [Internet]. 125, 306312 (2013). In this work, we propose a new machine learning approach [Variational Autoencoder Modular Bayesian Network (VAMBN)] to learn a generative model of longitudinal clinical study data. In GCPR. However, the current fastest method for alerting electromagnetic follow-up observers can provide estimates in of the order of 1min on a limited range of key source parameters. parameters defining each component per dimension]. In the area of Big Data, one of the major obstacles for the progress of biomedical research is the existence of data "silos" because legal and ethical constraints often do not allow for sharing sensitive patient data from clinical studies across institutions. https://doi.org/10.1145/2783258.2783273, pp 12351244, Li S, Kawale J, Fu Y (2015) Deep collaborative filtering via marginalized denoising auto-encoder.

Next, you'll compare these results to a more Bayesian approach, the VAE. The most famous example of gradient-based VI is probably the variational autoencoder.

An other way of getting insights into the latent space is to use the generator network to plot reconstructions at the positions in the latent space for which they have been generated: The figure below visualizes the data generated by the decoder network of a variational autoencoder trained on our dataset. An alternative approach to PMF is a Bayesian PMF model that suggests the Markov chain Monte Carlo algorithm as a full estimation for approximate intractable posterior over model parameters.
