Direct Evolutionary Optimization of Variational Autoencoders With Binary Latents

no code implementations27 Nov 2020 Enrico Guiraud, Jakob Drefs, Jörg Lücke

Discrete latent variables are considered important for real world data, which has motivated research on Variational Autoencoders (VAEs) with discrete latents.

Generic Unsupervised Optimization for a Latent Variable Model With Exponential Family Observables

1 code implementation4 Mar 2020 Hamid Mousavi, Jakob Drefs, Florian Hirschberger, Jörg Lücke

Here, we consider LVMs that are defined for a range of different distributions, i. e., observables can follow any (regular) distribution of the exponential family.

ProSper -- A Python Library for Probabilistic Sparse Coding with Non-Standard Priors and Superpositions

no code implementations1 Aug 2019 Georgios Exarchakis, Jörg Bornschein, Abdul-Saboor Sheikh, Zhenwen Dai, Marc Henniges, Jakob Drefs, Jörg Lücke

The library widens the scope of dictionary learning approaches beyond implementations of standard approaches such as ICA, NMF or standard L1 sparse coding.

Evolutionary Expectation Maximization for Generative Models with Binary Latents

no code implementations ICLR 2018 Enrico Guiraud, Jakob Drefs, Joerg Luecke

In general we believe that, with the link established here, standard as well as recent results in the field of evolutionary optimization can be leveraged to address the difficult problem of parameter optimization in generative models.
