Think before you act: A simple baseline for compositional generalization

1 code implementation29 Sep 2020 Christina Heinze-Deml, Diane Bouchacourt

Contrarily to humans who have the ability to recombine familiar expressions to create novel ones, modern neural networks struggle to do so.

Active Invariant Causal Prediction: Experiment Selection through Stability

2 code implementations NeurIPS 2020 Juan L. Gamella, Christina Heinze-Deml

A fundamental difficulty of causal learning is that causal models can generally not be fully identified based on observational data only.

Active Learning

Invariance-inducing regularization using worst-case transformations suffices to boost accuracy and spatial robustness

no code implementations NeurIPS 2019 Fanny Yang, Zuowen Wang, Christina Heinze-Deml

This work provides theoretical and empirical evidence that invariance-inducing regularizers can increase predictive accuracy for worst-case spatial transformations (spatial robustness).

Grouping-By-ID: Guarding Against Adversarial Domain Shifts

no code implementations ICLR 2018 Christina Heinze-Deml, Nicolai Meinshausen

If two or more samples share the same class and identifier, (Y, ID)=(y, i), then we treat those samples as counterfactuals under different style interventions on the orthogonal or style features.

Conditional Variance Penalties and Domain Shift Robustness

1 code implementation31 Oct 2017 Christina Heinze-Deml, Nicolai Meinshausen

Our goal is to minimize a loss that is robust under changes in the distribution of these style features.

Causal Structure Learning

no code implementations28 Jun 2017 Christina Heinze-Deml, Marloes H. Maathuis, Nicolai Meinshausen

Causal models can be viewed as a special class of graphical models that not only represent the distribution of the observed system but also the distributions under external interventions.

Invariant Causal Prediction for Nonlinear Models

1 code implementation26 Jun 2017 Christina Heinze-Deml, Jonas Peters, Nicolai Meinshausen

In this work, we present and evaluate an array of methods for nonlinear and nonparametric versions of ICP for learning the causal parents of given target variables.
