Multiply-Robust Causal Change Attribution

no code implementations12 Apr 2024 Victor Quintas-Martinez, Mohammad Taha Bahadori, Eduardo Santiago, Jeff Mu, Dominik Janzing, David Heckerman

Comparing two samples of data, we observe a change in the distribution of an outcome variable.

End-to-End Balancing for Causal Continuous Treatment-Effect Estimation

no code implementations27 Jul 2021 Mohammad Taha Bahadori, Eric Tchetgen Tchetgen, David E. Heckerman

In the process of optimization, these weights are automatically tuned to the specific dataset and causal inference algorithm being used.

Improving Generalizability of Protein Sequence Models via Data Augmentations

no code implementations1 Jan 2021 Hongyu Shen, Layne C. Price, Mohammad Taha Bahadori, Franziska Seeger

While protein sequence data is an emerging application domain for machine learning methods, small modifications to protein sequences can result in difficult-to-predict changes to the protein's function.

Debiasing Concept-based Explanations with Causal Analysis

no code implementations ICLR 2021 Mohammad Taha Bahadori, David E. Heckerman

Concept-based explanation approach is a popular model interpertability tool because it expresses the reasons for a model's predictions in terms of concepts that are meaningful for the domain experts.

Discovering Invariances in Healthcare Neural Networks

no code implementations8 Nov 2019 Mohammad Taha Bahadori, Layne C. Price

We also analyze the invariances of BioBERT on clinical notes and discover words that it is invariant to.

Temporal-Clustering Invariance in Irregular Healthcare Time Series

no code implementations27 Apr 2019 Mohammad Taha Bahadori, Zachary Chase Lipton

We postulate that fine temporal detail, e. g., whether a series of blood tests are completed at once or in rapid succession should not alter predictions based on this data.
