Learning disentangled representations for counterfactual regression. 2019. Learning-representations-for-counterfactual-inference - Github Our deep learning algorithm significantly outperforms the previous state-of-the-art. We perform experiments that demonstrate that PM is robust to a high level of treatment assignment bias and outperforms a number of more complex state-of-the-art methods in inferring counterfactual outcomes across several benchmark datasets. For each sample, we drew ideal potential outcomes from that Gaussian outcome distribution ~yjN(j,j)+ with N(0,0.15). On IHDP, the PM variants reached the best performance in terms of PEHE, and the second best ATE after CFRNET.

A comparison of methods for model selection when estimating We perform extensive experiments on semi-synthetic, real-world data in settings with two and more treatments. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. We calculated the PEHE (Eq. We consider the task of answering counterfactual questions such as, Navigate to the directory containing this file. general, not all the observed variables are confounders which are the common By modeling the different relations among variables, treatment and outcome, we Learning Disentangled Representations for CounterFactual Regression This is sometimes referred to as bandit feedback (Beygelzimer et al.,2010). stream Bengio, Yoshua, Courville, Aaron, and Vincent, Pierre.

PM may be used for settings with any amount of treatments, is compatible with any existing neural network architecture, simple to implement, and does not introduce any additional hyperparameters or computational complexity. The ACM Digital Library is published by the Association for Computing Machinery. In addition to a theoretical justification, we perform an empirical comparison with previous approaches to causal inference from observational data. Wager, Stefan and Athey, Susan. Domain adaptation for statistical classifiers. !lTv[ sj Note: Create a results directory before executing Run.py. 2011. Use of the logistic model in retrospective studies. We also found that the NN-PEHE correlates significantly better with real PEHE than MSE, that including more matched samples in each minibatch improves the learning of counterfactual representations, and that PM handles an increasing treatment assignment bias better than existing state-of-the-art methods.

NPCI: Non-parametrics for causal inference, 2016. confounders, ignoring the identification of confounders and non-confounders. Inference on counterfactual distributions. We can not guarantee and have not tested compability with Python 3. The conditional probability p(t|X=x) of a given sample x receiving a specific treatment t, also known as the propensity score Rosenbaum and Rubin (1983), and the covariates X themselves are prominent examples of balancing scores Rosenbaum and Rubin (1983); Ho etal. To ensure that differences between methods of learning counterfactual representations for neural networks are not due to differences in architecture, we based the neural architectures for TARNET, CFRNETWass, PD and PM on the same, previously described extension of the TARNET architecture Shalit etal. The ATE measures the average difference in effect across the whole population (Appendix B). Create a folder to hold the experimental results. Here, we present Perfect Match (PM), a method for training neural networks for counterfactual inference that is easy to implement, compatible with any architecture, does not add computational complexity or hyperparameters, and extends to any number of treatments. << /Filter /FlateDecode /Length1 1669 /Length2 8175 /Length3 0 /Length 9251 >> We found that PM handles high amounts of assignment bias better than existing state-of-the-art methods. His general research interests include data-driven methods for natural language processing, representation learning, information theory, and statistical analysis of experimental data. As a Research Staff Member of the Collaborative Research Center on Information Density and Linguistic Encoding, he analyzes cross-level interactions between vector-space representations of linguistic units. In addition to a theoretical justification, we perform an empirical comparison with previous approaches to causal inference from observational data.

Perfect Match: A Simple Method for Learning Representations For M.Blondel, P.Prettenhofer, R.Weiss, V.Dubourg, J.Vanderplas, A.Passos, Since the original TARNET was limited to the binary treatment setting, we extended the TARNET architecture to the multiple treatment setting (Figure 1). For low-dimensional datasets, the covariates X are a good default choice as their use does not require a model of treatment propensity. Here, we present Perfect Match (PM), a method for training neural networks for counterfactual inference that is easy to implement, compatible with any architecture, does not add computational complexity or hyperparameters, and extends to any number of treatments. Federated unsupervised representation learning, FITEE, 2022. This work was partially funded by the Swiss National Science Foundation (SNSF) project No. We found that PM better conforms to the desired behavior than PSMPM and PSMMI.
