5.1.93/nob Systematicity in the Vision to Language Chain
general concepts from the perception of particular instances and to instantiate thoseconcepts to new (or old) instances. Whether or not the network had actually met with a training case of bRa having already been shown a case of aRb, is of much less importance than itsability to perform concept abstraction since it is the latter which achieves systematicity andcompositionality. As f...
متن کاملIntentional Identity and Information Exchange Hob-nob Sentences
\We have intentional identity when a number of people, or one person on diierent occasions, have attitudes with a common focus, whether or not there actually is something at that focus" (Geach 1967, p. 627). In this paper we compare and relate Robert van Rooy's recent analysis of intentional identity descriptions by means of`Hob-Nob sentences', with Paul Dekker's equally recent analysis of cros...
متن کاملNob Mice Wave Goodbye to Eye-Specific Segregation
Spontaneous retinal activity is necessary to establish and maintain eye-specific projections to the LGN, but whether the spatial and temporal structure of this activity is important remains unclear. A new study by Demas et al. in the current issue of Neuron shows that when the frequency of spontaneous retinal waves is increased and waves abnormally persist past eye opening, eye-specific project...
متن کاملFailure to Maintain Eye-Specific Segregation in nob, a Mutant with Abnormally Patterned Retinal Activity
Axon terminals from the two eyes initially overlap in the dorsal-lateral geniculate nucleus (dLGN) but subsequently refine to occupy nonoverlapping territories. Retinal activity is required to establish and maintain this segregation. We show that despite the presence of retinal activity, segregated projections desegregate when the structure of activity is altered. Early in development, spontane...
متن کاملIdentification of the gene and the mutation responsible for the mouse nob phenotype.
PURPOSE The available evidence indicates that the naturally occurring mouse mutant nob (no b-wave) provides an animal model for the complete form of human X-linked congenital stationary night blindness (CSNB1). The goals of the present study were to identify the nob gene defect, to characterize the expression pattern of the involved gene, and to assess visual sensitivity in nob mice. METHODS ...
