WebMarr's account of the analysis of complex information-processing tasks as having three levels — the levels of computational theory, representation and algorithm, and hardware implementation — is reconsidered. I argue that the notion of “level” here runs together two distinctive sort of explanatory shifts — that of grain and that of ... WebVision must be understood at three dif-ferent levels: the computational level, the algorithmic level, and the level of implementation. His central claim is that the computational level is crucial for understanding vision (Marr 1982, p. 330). What is a "com-putational" level theory? Marr's use of the term "computational" is some-what unusual. perks plus giant eagle
