Inferring Heterogeneous Causal Effects in Presence of Spatial Confounding

ICML 2019oral

We address the problem of inferring the causal effect of an exposure on an outcome across space, using observational data. The data is possibly subject to unmeasured confounding variables which, in a standard approach, must be adjusted for by estimating a nuisance function. Here we develop a method…

Prediction of Spatial Point Processes: Regularized Method with Out-of-Sample Guarantees

NeurIPS 2019poster

A spatial point process can be characterized by an intensity function which predicts the number of events that occur across space. In this paper, we develop a method to infer predictive intensity intervals by learning a spatial model using a regularized criterion. We prove that the proposed method e…

Learning Localized Spatio-Temporal Models From Streaming Data

ICML 2018oral

We address the problem of predicting spatio-temporal processes with temporal patterns that vary across spatial regions, when data is obtained as a stream. That is, when the training dataset is augmented sequentially. Specifically, we develop a localized spatio-temporal covariance model of the proces…

Unsupervised Cipher Cracking Using Discrete GANs

ICLR 2018poster

This work details CipherGAN, an architecture inspired by CycleGAN used for inferring the underlying cipher mapping given banks of unpaired ciphertext and plaintext. We demonstrate that CipherGAN is capable of cracking language data enciphered using shift and Vigenere ciphers to a high degree of fide…
