Benchmarking Observational Studies with Experimental Data under Right-Censoring

no code implementations23 Feb 2024 Ilker Demirel, Edward De Brouwer, Zeshan Hussain, Michael Oberst, Anthony Philippakis, David Sontag

Drawing causal inferences from observational studies (OS) requires unverifiable validity assumptions; however, one can falsify those assumptions by benchmarking the OS with experimental data from a randomized controlled trial (RCT).

Conformalized Unconditional Quantile Regression

no code implementations4 Apr 2023 Ahmed M. Alaa, Zeshan Hussain, David Sontag

We develop a predictive inference procedure that combines conformal prediction (CP) with unconditional quantile regression (QR) -- a commonly used tool in econometrics that involves regressing the recentered influence function (RIF) of the quantile functional over input covariates.

Falsification of Internal and External Validity in Observational Studies via Conditional Moment Restrictions

no code implementations30 Jan 2023 Zeshan Hussain, Ming-Chieh Shih, Michael Oberst, Ilker Demirel, David Sontag

Our approach is interpretable, allowing a practitioner to visualize which subgroups in the population lead to falsification of an observational study.

Falsification before Extrapolation in Causal Effect Estimation

1 code implementation27 Sep 2022 Zeshan Hussain, Michael Oberst, Ming-Chieh Shih, David Sontag

Under the assumption that at least one observational estimator is asymptotically normal and consistent for both the validation and extrapolated effects, we provide guarantees on the coverage probability of the intervals output by our algorithm.

Using Time-Series Privileged Information for Provably Efficient Learning of Prediction Models

1 code implementation28 Oct 2021 Rickard K. A. Karlsson, Martin Willbo, Zeshan Hussain, Rahul G. Krishnan, David Sontag, Fredrik D. Johansson

Our question is when using this privileged data leads to more sample-efficient learning of models that use only baseline data for predictions at test time.

Neural Pharmacodynamic State Space Modeling

2 code implementations22 Feb 2021 Zeshan Hussain, Rahul G. Krishnan, David Sontag

Modeling the time-series of high-dimensional, longitudinal data is important for predicting patient disease progression.

Learning to Compose Domain-Specific Transformations for Data Augmentation

1 code implementation NeurIPS 2017 Alexander J. Ratner, Henry R. Ehrenberg, Zeshan Hussain, Jared Dunnmon, Christopher Ré

Data augmentation is a ubiquitous technique for increasing the size of labeled training sets by leveraging task-specific data transformations that preserve class labels.

Bidirectional American Sign Language to English Translation

no code implementations10 Jan 2017 Hardie Cate, Zeshan Hussain

We outline a bidirectional translation system that converts sentences from American Sign Language (ASL) to English, and vice versa.

DeepFace: Face Generation using Deep Learning

no code implementations7 Jan 2017 Hardie Cate, Fahim Dalvi, Zeshan Hussain

We use CNNs to build a system that both classifies images of faces based on a variety of different facial attributes and generates new faces given a set of desired facial characteristics.

Group Visual Sentiment Analysis

no code implementations7 Jan 2017 Zeshan Hussain, Tariq Patanam, Hardie Cate

In this paper, we introduce a framework for classifying images according to high-level sentiment.
