Disentangling shared and private latent factors in multimodal Variational Autoencoders

1 code implementation10 Mar 2024 Kaspar Märtens, Christopher Yau

Common or shared factors could be important for explaining variation across modalities whereas other factors may be private and important only for the explanation of a single modality.

Neural Decomposition: Functional ANOVA with Variational Autoencoders

1 code implementation25 Jun 2020 Kaspar Märtens, Christopher Yau

Our goal is to provide a feature-level variance decomposition, i. e. to decompose variation in the data by separating out the marginal additive effects of latent variables z and fixed inputs c from their non-linear interactions.

BasisVAE: Translation-invariant feature-level clustering with Variational Autoencoders

1 code implementation6 Mar 2020 Kaspar Märtens, Christopher Yau

Variational Autoencoders (VAEs) provide a flexible and scalable framework for non-linear dimensionality reduction.

Decomposing feature-level variation with Covariate Gaussian Process Latent Variable Models

2 code implementations16 Oct 2018 Kaspar Märtens, Kieran R. Campbell, Christopher Yau

The interpretation of complex high-dimensional data typically requires the use of dimensionality reduction techniques to extract explanatory low-dimensional representations.

Augmented Ensemble MCMC sampling in Factorial Hidden Markov Models

no code implementations24 Mar 2017 Kaspar Märtens, Michalis K. Titsias, Christopher Yau

Bayesian inference for factorial hidden Markov models is challenging due to the exponentially sized latent variable space.
