To many, the poster child for David Marr's famous three levels of scientific inquiry is reinforcement learning-a computational theory of reward optimization, which readily prescribes algorithmic solutions that evidence striking resemblance to signals found in the brain, suggesting a straightforward neural implementation. Here we review questions that remain open at each level of analysis, concluding that the path forward to their resolution calls for inspiration across levels, rather than a focus on mutual constraints.
对许多人来说，大卫·马尔著名的三个科学探究层次的典型代表是强化学习——一种奖励优化的计算理论，它很容易给出算法解决方案，这些方案与大脑中发现的信号惊人地相似，这表明有一种直接的神经实现方式。在这里，我们回顾了在每个分析层次上仍然悬而未决的问题，得出结论：解决这些问题的前进道路需要跨层次的启发，而不是专注于相互约束。
