CoRe: Conditional Variance Penalties and Domain Shift Robustness

TensorFlow implementation

TensorFlow implementation of 'CoRe' (COnditional Variance REgularization), proposed in "Conditional Variance Penalties and Domain Shift Robustness". The aim is to build classifiers that are robust against specific interventions. These domain-shift interventions are defined in a causal graph, extending the framework of Gong et al (2016). In contrast to Gong et al. we work on a setting where the domain variable itself is latent but we can observe for some instances a so-called identifier variables that indicates, for example, presence of the same person or object across different images. Penalizing the variance of the predictions across instances that share the same class label and identifier leads to robustness against strong domain-shift interventions.


R package

Code for 'nonlinear Invariant Causal Prediction' to estimate the causal parents of a given target variable from data collected in different experimental or environmental conditions, extending 'Invariant Causal Prediction' from Peters, Buehlmann and Meinshausen (2016) to nonlinear settings.


R package

Code for a variety of nonlinear conditional independence tests: Kernel conditional independence test (Zhang et al., UAI 2011), Residual Prediction test (based on Shah and Buehlmann, arXiv 2015), Invariant environment prediction, Invariant target prediction, Invariant residual distribution test, Invariant conditional quantile prediction (all from Heinze-Deml et al., arXiv:1706.08576).
