David Courtenay Marr (19 January 1945 – 17 November 1980) was a British neuroscientist and physiologist. Marr integrated results from psychology, artificial intelligence, and neurophysiology into new models of visual processing. His work was very influential in computational neuroscience and led to a resurgence of interest in the ...
David Marr fue un científico brillante que tuvo una influencia importante sobre varias áreas de la neurobiología teórica. Se añade a su leyenda era su muerte extemporánea en el cúlmen de su productividad. Comenzó su carrera con varios trabajos impresionantes que modelan el cerebelo y corteza cerebral (Marr, 1969, 1970).
Este autor distingue el nivel biológico (o físico), el nivel simbólico (o sintáctico o funcional) y el nivel semántico o intencional, equivalentes respectivamente a los niveles implementacional, algorítmico y computacional de Marr.
David Marr's posthumously published Vision (1982) influenced a generation of brain and cognitive scientists, inspiring many to enter the field. In Vision, Marr describes a general framework for understanding visual perception and touches on broader questions about how the brain and its functions can be studied and understood.

23 de abr. de 2015 · In 1982, David Marr advocated for three independent levels of understanding for any information-processing device, like the human brain: the level of computational theory, the level of representation and algorithm, and the level of hardware implementation (p. 25).

5 de jun. de 2007 · Of his ‘theoretical maxims’, the best known is Marr's argument that problems in neuroscience must be tackled at a number of different levels: computational theory, algorithm and implementation. Computational theory means making explicit the input and output of a process and the constraints that would allow the problem to be solved.
