Prototypical Variational Autoencoders

no code implementations29 Sep 2021 Dario Augusto Borges Oliveira, Laura Elena Cue La Rosa

Variational autoencoders are unsupervised generative models that implement latent space regularization towards a known distribution, enabling stochastic synthesis from straightforward sampling procedures.

Controlling Weather Field Synthesis Using Variational Autoencoders

no code implementations30 Jul 2021 Dario Augusto Borges Oliveira, Jorge Guevara Diaz, Bianca Zadrozny, Campbell Watson

One of the consequences of climate change is anobserved increase in the frequency of extreme cli-mate events.

Decoupling Shape and Density for Liver Lesion Synthesis Using Conditional Generative Adversarial Networks

no code implementations1 Jun 2021 Dario Augusto Borges Oliveira

Lesion synthesis received much attention with the rise of efficient generative models for augmenting training data, drawing lesion evolution scenarios, or aiding expert training.

An argument in favor of strong scaling for deep neural networks with small datasets

no code implementations24 Jul 2018 Renato L. de F. Cunha, Eduardo R. Rodrigues, Matheus Palhares Viana, Dario Augusto Borges Oliveira

We evaluated our approach with up to 32 GPUs and show that weak scaling not only does not have the same accuracy as the sequential model, it also fails to converge most of time.

Automatic tracking of vessel-like structures from a single starting point

no code implementations8 Jun 2017 Dario Augusto Borges Oliveira, Laura Leal-Taixe, Raul Queiroz Feitosa, Bodo Rosenhahn

Further visual results also show the potential of our approach for identifying vascular networks topologies.
