MARR: Active vision model
Earlier13,18,19, the biologically plausible active vision ,model for Multiresolutional Attentional Representation and Recognition (MARR) has been developed. The model is based on the scanpath theory of Noton and Stark17and provides invariant recognition of gray-level images. In the present paper, the algorithm of automatic image viewing trajectory formation in the MARR model, the results of psy...
متن کاملReinforcement learning with Marr.
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, concl...
متن کاملMarR family transcription factors
Figure 1. Representative MarR homologs and their mode of gene regulation. (A) Structure of MTH313 (3BPX), a MarR homolog of unknown function from Methanobacterium thermoautotrophicum, in complex with the ligand salicylate (shown in magenta). One monomer is shown in gray, the other is colored from amino to carboxyl terminus (blue to red). Note the asymmetrical ligand binding; only ligand binding...
متن کاملMarr on Computational-Level Theories*
properties of B1 and B2. Ideally, this mapping relation is defined in terms of mathematical properties abstracted from the electrical activity of the cells: “At one extreme, the top level, is the abstract computational theory of the device, in which the performance of the device is characterized as a mapping from one kind of information to another, the abstract properties of this mapping are de...
متن کاملMemory, modelling and Marr: a commentary on Marr (1971) ‘Simple memory: a theory of archicortex’
David Marr's theory of the archicortex, a brain structure now more commonly known as the hippocampus and hippocampal formation, is an epochal contribution to theoretical neuroscience. Addressing the problem of how information about 10 000 events could be stored in the archicortex during the day so that they can be retrieved using partial information and then transferred to the neocortex overnig...
