Simultanagnosia: When a Rose Is Not Red

Abstract Information regarding object identity ("what") and spatial location ("where/how to") is largely segregated in visual processing. Under most circumstances, however, object identity and location are linked. We report data from a simultanagnosic patient (K.E.) with bilateral posterior parietal infarcts who was unable to "see" more than one object in an array despite relatively preserved o...

White Rose Consortium ePrints Repository

In this paper we evaluate a selection of data retrieval algorithms for storage e ciency retrieval speed and partial matching capabilities using a large information retrieval dataset We evaluate standard data structures for example inverted le lists and hash tables but also a novel binary neu ral network that incorporates single epoch training superimposed coding and associative matching in a bi...

Published case studies have used different computational approaches. This paper examines the computation of partial EVPI estimates via Monte-Carlo sampling algorithms. Our mathematical definition shows two nest...
