Counterfactual Explanations for Multivariate Time-Series without Training Datasets

no code implementations28 May 2024 Xiangyu Sun, Raquel Aoki, Kevin H. Wilson

However, most existing CFE methods require access to the model's training dataset, few methods can handle multivariate time-series, and none can handle multivariate time-series without training datasets.

Causal Inference from Small High-dimensional Datasets

no code implementations19 May 2022 Raquel Aoki, Martin Ester

Our experiments show that such an approach helps to bring stability to neural network-based methods and improve the treatment effect estimates in small high-dimensional datasets.

Heterogeneous Multi-task Learning with Expert Diversity

1 code implementation20 Jun 2021 Raquel Aoki, Frederick Tung, Gabriel L. Oliveira

In contrast to single-task learning, in which a separate model is trained for each target, multi-task learning (MTL) optimizes a single model to predict multiple related targets simultaneously.

ParKCa: Causal Inference with Partially Known Causes

1 code implementation17 Mar 2020 Raquel Aoki, Martin Ester

Methods for causal inference from observational data are an alternative for scenarios where collecting counterfactual data or realizing a randomized experiment is not possible.
