Learned transform compression with optimized entropy encoding

1 code implementation ICLR Workshop Neural_Compression 2021 Magda Gregorová, Marc Desaules, Alexandros Kalousis

We consider the problem of learned transform compression where we learn both, the transform as well as the probability distribution over the discrete codes.

Improving VAE generations of multimodal data through data-dependent conditional priors

no code implementations25 Nov 2019 Frantzeska Lavda, Magda Gregorová, Alexandros Kalousis

We propose a novel formulation of variational autoencoders, conditional prior VAE (CP-VAE), which learns to differentiate between the individual mixture components and therefore allows for generations from the distributional data clusters.

Structured nonlinear variable selection

1 code implementation16 May 2018 Magda Gregorová, Alexandros Kalousis, Stéphane Marchand-Maillet

We investigate structured sparsity methods for variable selection in regression problems where the target depends nonlinearly on the inputs.

Forecasting and Granger Modelling with Non-linear Dynamical Dependencies

1 code implementation27 Jun 2017 Magda Gregorová, Alexandros Kalousis, Stéphane Marchand-Maillet

Traditional linear methods for forecasting multivariate time series are not able to satisfactorily model the non-linear dependencies that may exist in non-Gaussian series.
