C-XGBoost: A tree boosting model for causal effect estimation

no code implementations31 Mar 2024 Niki Kiriakidou, Ioannis E. Livieris, Christos Diou

Causal effect estimation aims at estimating the Average Treatment Effect as well as the Conditional Average Treatment Effect of a treatment to an outcome from the available data.

Explainable Image Similarity: Integrating Siamese Networks and Grad-CAM

1 code implementation11 Oct 2023 Ioannis E. Livieris, Emmanuel Pintelas, Niki Kiriakidou, Panagiotis Pintelas

In this paper, we propose the concept of explainable image similarity, where the goal is the development of an approach, which is capable of providing similarity scores along with visual factual and counterfactual explanations.

Integrating Nearest Neighbors with Neural Network Models for Treatment Effect Estimation

no code implementations11 May 2023 Niki Kiriakidou, Christos Diou

The proposed NNCI methodology is applied to some of the most well established neural network-based models for treatment effect estimation with the use of observational data.

Causal Inference

An evaluation framework for comparing causal inference models

no code implementations31 Aug 2022 Niki Kiriakidou, Christos Diou

In this paper, we propose to complement the evaluation of causal inference models using concrete statistical evidence, including the performance profiles of Dolan and Mor{\'e}, as well as non-parametric and post-hoc statistical tests.
