研究人员推出了一种新颖的贝叶斯实验设计框架 Action-BED，它将目标从不确定性降低重新表述为下游动作的预期未来损失。这种方法允许使用随机梯度进行优化的单次难解目标，从而简化了设计策略的学习过程。Action-BED 还为各种下游任务和损失函数提供了更轻松的定制，无需显式估计后验或边际似然。 AI

影响为机器学习中的实验设计策略优化引入了一种更有效、更可定制的方法。

Action-BED: Task-Driven Bayesian Experimental Design with Singly Intractable Objectives

Bayesian experimental design (BED) has traditionally been based on maximising expected uncertainty reductions from prior to posterior. A major shortfall of this approach is that it leads to doubly intractable objectives that are difficult to optimise, while customising them to pa…
