Variational Data Assimilation with a Learned Inverse Observation Operator

1 code implementation22 Feb 2021 Thomas Frerix, Dmitrii Kochkov, Jamie A. Smith, Daniel Cremers, Michael P. Brenner, Stephan Hoyer

Variational data assimilation optimizes for an initial state of a dynamical system such that its evolution fits observational data.

Homogeneous Linear Inequality Constraints for Neural Network Activations

1 code implementation5 Feb 2019 Thomas Frerix, Matthias Nießner, Daniel Cremers

One way to achieve this task is by means of a projection step at test time after unconstrained training.

Associative Domain Adaptation

2 code implementations ICCV 2017 Philip Haeusser, Thomas Frerix, Alexander Mordvintsev, Daniel Cremers

Our training scheme follows the paradigm that in order to effectively derive class labels for the target domain, a network should produce statistically domain invariant embeddings, while minimizing the classification error on the labeled source domain.

Proximal Backpropagation

1 code implementation ICLR 2018 Thomas Frerix, Thomas Möllenhoff, Michael Moeller, Daniel Cremers

Specifically, we show that backpropagation of a prediction error is equivalent to sequential gradient descent steps on a quadratic penalty energy, which comprises the network activations as variables of the optimization.
