Causal Artificial Intelligence: Modeling Cause-Effect Relationships for Intelligent Decision Systems

Abstract: Artificial Intelligence (AI) has become an essential technology in healthcare, finance, recommendation systems, forecasting, autonomous systems, and decision-making applications. Most traditional AI systems are based on correlation-driven machine learning techniques that identify patterns from historical data. Although these systems achieve high prediction accuracy, they fail to explain the actual reasoning behind decisions, resulting in lack of transparency, trust, fairness, and robustness. This limitation becomes critical in high-stakes applications where explainability and accountability are important.

Causal Artificial Intelligence (Causal AI) addresses these limitations by introducing cause-effect reasoning into AI systems. Unlike conventional AI models, Causal AI can answer “why,” “what-if,” and “what would have happened differently” questions using causal inference and counterfactual reasoning. This paper presents a comprehensive literature survey of eighteen research papers related to causal inference, explainable AI, deep causal learning, causal machine learning, ethical AI, and forecasting systems. The study analyzes methodologies, models, algorithms, challenges, limitations, and future research directions.

The literature survey identifies several important techniques including Structural Causal Models (SCM), Directed Acyclic Graphs (DAG), Double Machine Learning (DML), Variational Autoencoders (VAE), Fuzzy Cognitive Maps (FCM), SHAP, and LIME. The results indicate that integrating causal reasoning with Machine Learning and Deep Learning significantly improves explainability, fairness, robustness, interpretability, and trustworthy decision-making in modern AI systems.
