Blokpoel reminds us of the importance of consistency of function across Marr's levels, but we argue that the approach to ensuring consistency that he advocates-a strict relation through exact implementation of the higher level function at the lower level-is unnecessarily restrictive. We show that it forces overcomplication of the computational level (by requiring it to incorporate concerns from lower levels) and results in the sacrifice of the distinct responsibilities associated with each level. We propose an alternative, no less rigorous, potential characterization of the relation between levels.
布洛克波尔提醒我们要注意在马氏层级中功能的一致性,但我们认为他所提倡的确保一致性的方法——通过在较低层次上精确实现较高层次的功能来建立严格的关系——过于局限。我们表明,这种方法迫使计算层次变得过于复杂(要求它纳入较低层次的问题),并导致与每个层次相关的明确职责的牺牲。我们提出了一种替代方法,一种同样严格的潜在的层级之间关系的特征化方法。
