Learning Partially Known Stochastic Dynamics with Empirical PAC Bayes

AISTATS 2021poster

Neural Stochastic Differential Equations model a dynamical environment with neural nets assigned to their drift and diffusion terms. The high expressive power of their nonlinearity comes at the expense of instability in the identification of the large set of free parameters. This paper presents a re…

LeMoNADe: Learned Motif and Neuronal Assembly Detection in calcium imaging videos

ICLR 2019poster

Neuronal assemblies, loosely defined as subsets of neurons with reoccurring spatio-temporally coordinated activation patterns, or "motifs", are thought to be building blocks of neural representations and information processing. We here propose LeMoNADe, a new exploratory data analysis method that fa…

Sampling-Free Variational Inference of Bayesian Neural Networks by Variance Backpropagation

UAI 2019poster

We propose a new Bayesian Neural Net formulation that affords variational inference for which the evidence lower bound is analytically tractable subject to a tight approximation. We achieve this tractability by (i) decomposing ReLU nonlinearities into the product of an identity and a Heaviside step…
