Counterfactual Learning with Multioutput Deep Kernels

1 code implementation20 Nov 2022 Alberto Caron, Gianluca Baio, Ioanna Manolopoulou

In this paper, we address the challenge of performing counterfactual inference with observational data via Bayesian nonparametric regression adjustment, with a focus on high-dimensional settings featuring multiple actions and multiple correlated outcomes.

Shrinkage Bayesian Causal Forests for Heterogeneous Treatment Effects Estimation

1 code implementation12 Feb 2021 Alberto Caron, Gianluca Baio, Ioanna Manolopoulou

This paper develops a sparsity-inducing version of Bayesian Causal Forests, a recently proposed nonparametric causal regression model that employs Bayesian Additive Regression Trees and is specifically designed to estimate heterogeneous treatment effects using observational data.

Estimating Individual Treatment Effects using Non-Parametric Regression Models: a Review

1 code implementation14 Sep 2020 Alberto Caron, Gianluca Baio, Ioanna Manolopoulou

Large observational data are increasingly available in disciplines such as health, economic and social sciences, where researchers are interested in causal questions rather than prediction.

Modelling Grocery Retail Topic Distributions: Evaluation, Interpretability and Stability

no code implementations4 May 2020 Mariflor Vega-Carrasco, Jason O'sullivan, Rosie Prior, Ioanna Manolopoulou, Mirco Musolesi

Our approach is an alternative to standard label-switching techniques and provides a single posterior summary set of topics, as well as associated measures of uncertainty.

BPEC: An R Package for Bayesian Phylogeographic and Ecological Clustering

1 code implementation6 Apr 2016 Ioanna Manolopoulou, Axel Hille, Brent Emerson

BPEC is an R package for Bayesian Phylogeographic and Ecological Clustering which allows geographical, environmental and phenotypic measurements to be combined with DNA sequences in order to reveal clustered structure resulting from migration events.
