Interpretable VAEs for nonlinear group factor analysis

no code implementations17 Feb 2018 Samuel Ainsworth, Nicholas Foti, Adrian KC Lee, Emily Fox

Deep generative models have recently yielded encouraging results in producing subjectively realistic samples of complex data.

Neural Granger Causality

3 code implementations16 Feb 2018 Alex Tank, Ian Covert, Nicholas Foti, Ali Shojaie, Emily Fox

We show that our neural Granger causality methods outperform state-of-the-art nonlinear Granger causality methods on the DREAM3 challenge data.

Variational Boosting: Iteratively Refining Posterior Approximations

1 code implementation ICML 2017 Andrew C. Miller, Nicholas Foti, Ryan P. Adams

We propose a black-box variational inference method to approximate intractable distributions with an increasingly rich approximating class.
