Empirical Analysis of Model Selection for Heterogeneous Causal Effect Estimation

1 code implementation3 Nov 2022 Divyat Mahajan, Ioannis Mitliagkas, Brady Neal, Vasilis Syrgkanis

We study the problem of model selection in causal inference, specifically for the case of conditional average treatment effect (CATE) estimation under binary treatments.

Towards efficient representation identification in supervised learning

1 code implementation10 Apr 2022 Kartik Ahuja, Divyat Mahajan, Vasilis Syrgkanis, Ioannis Mitliagkas

In this work, we depart from these assumptions and ask: a) How can we get disentanglement when the auxiliary information does not provide conditional independence over the factors of variation?

The Connection between Out-of-Distribution Generalization and Privacy of ML Models

1 code implementation7 Oct 2021 Divyat Mahajan, Shruti Tople, Amit Sharma

Through extensive evaluation on a synthetic dataset and image datasets like MNIST, Fashion-MNIST, and Chest X-rays, we show that a lower OOD generalization gap does not imply better robustness to MI attacks.

Split-Treatment Analysis to Rank Heterogeneous Causal Effects for Prospective Interventions

no code implementations11 Nov 2020 Yanbo Xu, Divyat Mahajan, Liz Manrao, Amit Sharma, Emre Kiciman

For many kinds of interventions, such as a new advertisement, marketing intervention, or feature recommendation, it is important to target a specific subset of people for maximizing its benefits at minimum cost or potential harm.

Towards Unifying Feature Attribution and Counterfactual Explanations: Different Means to the Same End

2 code implementations10 Nov 2020 Ramaravind Kommiya Mothilal, Divyat Mahajan, Chenhao Tan, Amit Sharma

In addition, by restricting the features that can be modified for generating counterfactual examples, we find that the top-k features from LIME or SHAP are often neither necessary nor sufficient explanations of a model's prediction.

Domain Generalization using Causal Matching

1 code implementation arXiv 2020 Divyat Mahajan, Shruti Tople, Amit Sharma

In the domain generalization literature, a common objective is to learn representations independent of the domain after conditioning on the class label.

Preserving Causal Constraints in Counterfactual Explanations for Machine Learning Classifiers

3 code implementations6 Dec 2019 Divyat Mahajan, Chenhao Tan, Amit Sharma

For explanations of ML models in critical domains such as healthcare and finance, counterfactual examples are useful for an end-user only to the extent that perturbation of feature inputs is feasible in the real world.

A Generative Framework for Zero-Shot Learning with Adversarial Domain Adaptation

1 code implementation7 Jun 2019 Varun Khare, Divyat Mahajan, Homanga Bharadhwaj, Vinay Verma, Piyush Rai

Our approach is based on end-to-end learning of the class distributions of seen classes and unseen classes.
