Semi-supervised Learning Approach to Generate Neuroimaging Modalities with Adversarial Training

no code implementations9 Dec 2019 Harrison Nguyen, Simon Luo, Fabio Ramos

On the other hand, there is smaller fraction of examples that contain all modalities (\emph{paired} data) and furthermore each modality is high dimensional when compared to number of datapoints.

When can we improve on sample average approximation for stochastic optimization?

no code implementations19 Jul 2019 Eddie Anderson, Harrison Nguyen

Here the sample average approximation is remarkably effective and only consistently outperformed by a Bayesian approach.
