15 صفحه اولInformation storage and retrieval in spin-glass like neural networks
2014 The link between the structure of a neural network and its attractor states is investigated, with a view to designing associative memories based on such networks. It is shown that, for any preassigned set of states to be memorized, the parameters of the network can be completely calculated in most cases so as to guaranteee the stability of these states. The spin glass formulation of the ne...
متن کاملBalanced Information Storage and Transfer in Modular Spiking Neural Networks
While information processing in complex systems can be described in abstract, general terms, there are cases in which the relation between these computations and the physical substrate of the underlying system is itself of interest. Prominently, the brain is one such case. With the aim of relating information and dynamics in biological neural systems, we study a model network of spiking neurons...
متن کاملTask demands control acquisition and storage of visual information.
Attention and working memory limitations set strict limits on visual representations, yet researchers have little appreciation of how these limits constrain the acquisition of information in ongoing visually guided behavior. Subjects performed a brick sorting task in a virtual environment. A change was made to 1 of the features of the brick being held on about 10% of trials. Rates of change det...
متن کاملInformation storage in neural networks with low levels of activity.
The Hopfield model of a neural network is extended to allow for the storage and retrieval of biased patterns, [g'";), where N 'g, g =a is arbitrary. Such patterns represent levels of activity (i.e., percentage of firing neurons) equal to 2 (1+a), —1 &a & 1. If the coupling constants (synaptic efficacies) are constructed as in the original Hopfield model, the system can retrieve at most a very s...
