Abstract

This paper investigates the application of quantum-inspired optimization techniques to the problem of inference and learning within large-scale Bayesian Networks (BNs). Traditional Bayesian Network learning and inference methods often struggle with scalability, particularly as the number of nodes and dependencies increases. We propose leveraging concepts from quantum algorithms, specifically drawing inspiration from quantum annealing and quantum Monte Carlo methods, to efficiently explore the complex search space associated with BN structure optimization and parameter estimation. The core idea is to mimic the exploration capabilities of quantum systems to accelerate the process. The proposed methodology aims to improve the efficiency of BN learning and inference, potentially unlocking new capabilities for probabilistic reasoning in complex systems. This work presents a theoretical framework and a conceptual outline for such an approach, laying the groundwork for future research and experimentation. The effectiveness of this approach is predicated on the ability to translate the inherent parallelism of quantum algorithms into an efficient optimization strategy for Bayesian Networks.

Quantum-Inspired Bayesian Inference for Causal Discovery

Jincheng Zhang

This paper introduces a novel approach to causal discovery leveraging principles inspired by quantum mechanics. Traditional Bayesian network learning methods often struggle with the vastness of possible causal structures, leading to computational bottlenecks and potentially inaccurate results. We propose a framework that incorporates probabilistic amplitudes, analogous to quantum superposition, to represent and explore multiple potential causal pathways concurrently. This "quantum-inspired" Bayesian inference aims to significantly enhance the exploration process, ultimately leading to improved accuracy in identifying causal relationships within observational data. The core idea is that by allowing for multiple potential pathways to be actively explored simultaneously, we can overcome the limitations of classical methods that typically rely on sequential searching. This approach is evaluated conceptually, outlining the key components and anticipated benefits. The paper focuses on the theoretical underpinnings and the potential impact of this methodology, paving the way for future research and development.
