GO-CBED：面向因果学习的目标导向序列贝叶斯实验设计框架
Goal-Oriented Sequential Bayesian Experimental Design for Causal Learning
AI 导读
GO-CBED 是一个目标导向的贝叶斯框架，用于序列因果实验设计，直接最大化用户指定因果量的期望信息增益（EIG），而非推断完整因果模型，并通过对整个干预序列进行非短视优化实现前瞻性规划。

Abstract:We present GO-CBED, a goal-oriented Bayesian framework for sequential causal experimental design. Unlike conventional approaches that select interventions aimed at inferring the full causal model, GO-CBED directly maximizes the expected information gain (EIG) on user-specified causal quantities of interest, enabling more targeted and efficient experimentation. The framework is both non-myopic, optimizing over entire intervention sequences, and goal-oriented, targeting only model aspects relevant to the causal query. To address the intractability of exact EIG computation, we introduce a variational lower bound estimator, optimized jointly through a transformer-based policy network and normalizing flow-based variational posteriors. The resulting policy enables real-time decision-making via an amortized network. We demonstrate that GO-CBED consistently outperforms existing baselines across various causal reasoning and discovery tasks-including synthetic structural causal models and semi-synthetic gene regulatory networks-particularly in settings with limited experimental budgets and complex causal mechanisms. Our results highlight the benefits of aligning experimental design objectives with specific research goals and of forward-looking sequential planning.
