Learned Causal Method Prediction

no code implementations7 Nov 2023 Shantanu Gupta, Cheng Zhang, Agrin Hilmkil

In this work, we propose CAusal Method Predictor (CAMP), a framework for predicting the best method for a given dataset.

Local Discovery by Partitioning: Polynomial-Time Causal Discovery Around Exposure-Outcome Pairs

no code implementations25 Oct 2023 Jacqueline Maasch, Weishen Pan, Shantanu Gupta, Volodymyr Kuleshov, Kyra Gan, Fei Wang

Causal discovery is crucial for causal inference in observational studies: it can enable the identification of valid adjustment sets (VAS) for unbiased effect estimation.

Local Causal Discovery for Estimating Causal Effects

1 code implementation16 Feb 2023 Shantanu Gupta, David Childers, Zachary C. Lipton

Even when the causal graph underlying our data is unknown, we can use observational data to narrow down the possible values that an average treatment effect (ATE) can take by (1) identifying the graph up to a Markov equivalence class; and (2) estimating that ATE for each graph in the class.

Discovering Optimal Scoring Mechanisms in Causal Strategic Prediction

no code implementations14 Feb 2023 Tom Yan, Shantanu Gupta, Zachary Lipton

While earlier works cast these manipulations as undesirable gaming, recent works have adopted a more nuanced causal framing in which manipulations can improve outcomes of interest, and setting coherent mechanisms requires accounting for both predictive accuracy and improvement of the outcome.

Eulerian Single-Photon Vision

no code implementations ICCV 2023 Shantanu Gupta, Mohit Gupta

Previous work has largely focused on solving the image reconstruction problem first and then using off-the-shelf methods for downstream tasks, but the most general solutions that account for motion are costly and not scalable to large data volumes produced by single-photon sensors.

Efficient Online Estimation of Causal Effects by Deciding What to Observe

1 code implementation NeurIPS 2021 Shantanu Gupta, Zachary C. Lipton, David Childers

Researchers often face data fusion problems, where multiple data sources are available, each capturing a distinct subset of variables.

Correcting Exposure Bias for Link Recommendation

1 code implementation13 Jun 2021 Shantanu Gupta, Hao Wang, Zachary C. Lipton, Yuyang Wang

Link prediction methods are frequently applied in recommender systems, e. g., to suggest citations for academic papers or friends in social networks.

Passive Inter-Photon Imaging

no code implementations CVPR 2021 Atul Ingle, Trevor Seets, Mauro Buttafava, Shantanu Gupta, Alberto Tosi, Mohit Gupta, Andreas Velten

Digital camera pixels measure image intensities by converting incident light energy into an analog electrical current, and then digitizing it into a fixed-width binary representation.

Quanta Burst Photography

no code implementations21 Jun 2020 Sizhuo Ma, Shantanu Gupta, Arin C. Ulku, Claudio Bruschini, Edoardo Charbon, Mohit Gupta

These single-photon cameras (SPCs) are capable of capturing high-speed sequences of binary single-photon images with no read noise.

Estimating Treatment Effects with Observed Confounders and Mediators

no code implementations26 Mar 2020 Shantanu Gupta, Zachary C. Lipton, David Childers

We show that it strictly outperforms the backdoor and frontdoor estimators and that this improvement can be unbounded.
