Counterfactual Reasoning Using Predicted Latent Personality Dimensions for Optimizing Persuasion Outcome

no code implementations21 Apr 2024 Donghuo Zeng, Roberto S. Legaspi, Yuewen Sun, Xinshuai Dong, Kazushi Ikeda, Peter Spirtes, Kun Zhang

In this paper, we present a novel approach that tracks a user's latent personality dimensions (LPDs) during ongoing persuasion conversation and generates tailored counterfactual utterances based on these LPDs to optimize the overall persuasion outcome.

Gene Regulatory Network Inference in the Presence of Dropouts: a Causal View

1 code implementation21 Mar 2024 Haoyue Dai, Ignavier Ng, Gongxu Luo, Peter Spirtes, Petar Stojanov, Kun Zhang

This particular test-wise deletion procedure, in which we perform CI tests on the samples without zeros for the conditioned variables, can be seamlessly integrated with existing structure learning approaches including constraint-based and greedy score-based methods, thus giving rise to a principled framework for GRNI in the presence of dropouts.

A Versatile Causal Discovery Framework to Allow Causally-Related Hidden Variables

no code implementations18 Dec 2023 Xinshuai Dong, Biwei Huang, Ignavier Ng, Xiangchen Song, Yujia Zheng, Songyao Jin, Roberto Legaspi, Peter Spirtes, Kun Zhang

Most existing causal discovery methods rely on the assumption of no latent confounders, limiting their applicability in solving real-life problems.

Procedural Fairness Through Decoupling Objectionable Data Generating Components

1 code implementation5 Nov 2023 Zeyu Tang, Jialu Wang, Yang Liu, Peter Spirtes, Kun Zhang

We reveal and address the frequently overlooked yet important issue of disguised procedural unfairness, namely, the potentially inadvertent alterations on the behavior of neutral (i. e., not problematic) aspects of data generating process, and/or the lack of procedural assurance of the greatest benefit of the least advantaged individuals.

Causal-learn: Causal Discovery in Python

1 code implementation31 Jul 2023 Yujia Zheng, Biwei Huang, Wei Chen, Joseph Ramsey, Mingming Gong, Ruichu Cai, Shohei Shimizu, Peter Spirtes, Kun Zhang

Causal discovery aims at revealing causal relations from observational data, which is a fundamental task in science and engineering.

Independence Testing-Based Approach to Causal Discovery under Measurement Error and Linear Non-Gaussian Models

no code implementations20 Oct 2022 Haoyue Dai, Peter Spirtes, Kun Zhang

Causal discovery under measurement error aims to recover the causal graph among unobserved target variables from observations made with measurement error.

The m-connecting imset and factorization for ADMG models

no code implementations18 Jul 2022 Bryan Andrews, Gregory F. Cooper, Thomas S. Richardson, Peter Spirtes

The m-connecting imset and factorization criterion provide two new statistical tools for learning and inference with ADMG models.

Causal discovery for observational sciences using supervised machine learning

1 code implementation25 Feb 2022 Anne Helby Petersen, Joseph Ramsey, Claus Thorn Ekstrøm, Peter Spirtes

We use random subsampling to investigate real data performance on small samples and again find that SLdisco is less sensitive towards sample size and hence seems to better utilize the information available in small datasets.

A Uniformly Consistent Estimator of non-Gaussian Causal Effects Under the k-Triangle-Faithfulness Assumption

no code implementations3 Jul 2021 Shuyan Wang, Peter Spirtes

Kalisch and B\"{u}hlmann (2007) showed that for linear Gaussian models, under the Causal Markov Assumption, the Strong Causal Faithfulness Assumption, and the assumption of causal sufficiency, the PC algorithm is a uniformly consistent estimator of the Markov Equivalence Class of the true causal DAG for linear Gaussian models; it follows from this that for the identifiable causal effects in the Markov Equivalence Class, there are uniformly consistent estimators of causal effects as well.

Learning from Positive and Unlabeled Data by Identifying the Annotation Process

no code implementations2 Mar 2020 Naji Shajarisales, Peter Spirtes, Kun Zhang

Yet the annotation process is an important part of the data collection, and in many cases it naturally depends on certain features of the data (e. g., the intensity of an image and the size of the object to be detected in the image).

Causal Discovery in the Presence of Measurement Error: Identifiability Conditions

no code implementations10 Jun 2017 Kun Zhang, Mingming Gong, Joseph Ramsey, Kayhan Batmanghelich, Peter Spirtes, Clark Glymour

This problem has received much attention in multiple fields, but it is not clear to what extent the causal model for the measurement-error-free variables can be identified in the presence of measurement error with unknown variance.

Mixed Graphical Models for Causal Analysis of Multi-modal Variables

1 code implementation9 Apr 2017 Andrew J Sedgewick, Joseph D. Ramsey, Peter Spirtes, Clark Glymour, Panayiotis V. Benos

Graphical causal models are an important tool for knowledge discovery because they can represent both the causal relations between variables and the multivariate probability distributions over the data.

This is the Proceedings of the Twenty-Sixth Conference on Uncertainty in Artificial Intelligence, which was held on Catalina Island, CA, July 8 - 11 2010.

Nonlinear directed acyclic structure learning with weakly additive noise models

no code implementations NeurIPS 2009 Arthur Gretton, Peter Spirtes, Robert E. Tillman

This results in a more computationally efficient approach that is useful for arbitrary distributions even when additive noise models are invertible.
