We investigate the dynamical properties of an associative memory network consisting of stochastic neurons and dynamic synapses that show short-term depression and facilitation. In the stochastic neuron model used in this study, the efficacy of the synaptic transmission changes according to the short-term depression or facilitation mechanism. We derive a macroscopic mean field model that capture...

This paper proposes an analytical cache model for time-shared systems focusing on fully-associative caches, which estimates the overall cache miss-rate from the isolated miss-rate curve of each process when multiple processes share a cache. Unlike previous models, our model works for any cache size and any time quantum. Trace-driven simulations demonstrate that the estimated miss-rate is very a...

A cellular analog of associative learning has been demonstrated in individual sensory neurons of the tail withdrawal reflex of Aplysia. Sensory cells activated by intracellular current injection shortly before a sensitizing shock to the animal's tail display significantly more facilitation of their monosynaptic connections to a tail motor neuron than cells trained either with intracellular stim...

How do people come to assign symbolic labels to continuous dimensions? Previous work has shown that prediction-errordriven models are sensitive to the order of labels and exemplars during training; similar patterns of learning are found found in adult learners trained to associate labels with discrete visual stimuli. Here we provide further evidence in support of the hypothesis that an error-dr...

A new model for associative memory with discrete time is proposed, in which chaos is taken into account and moreover the internal state of neurons depends on the past history. The network itself can search for minima of the energy successively by using the wandering motion and co-operative phenomena. By using this model we can clearly discuss the mechanism or the dynamics of the wandering motio...

This paper describes Constrained Associative-Mapping-of-Tracking-Entries (C-AMTE), a scalable mechanism to facilitate flexible and efficient distributed cache management in large-scale chip multiprocessors (CMPs). C-AMTE enables fast locating of cache blocks in CMP cache schemes that employ one-to-one or one-to-many associative mappings. C-AMTE stores in percore data structures tracking entries...

The problem of integrating territorial information within a multisensor vision system for autonomous-vehicle control is addressed. Environmental information is used to improve recognition results and to locate a vehicle's position in the coordinate reference frame of a map. To this end, a hypothesis-and-test search mechanism has been developed, which is based on an associative phase and a symbo...

The accessibility based framework proposed by Recanati (2004) aims at explaining the output of primary pragmatic processes in entirely associative terms. This attempt has been challenged by the relevance-theoretic position that selection of meaning components is directed by considerations of relevance and not by accessibility alone. The key question concerns the extent to which an associative m...

in this work, we describe an adjunction between the comma category of set-based monads under the v -powerset monad and the category of associative lax extensions of set-based monads to the category of v -relations. in the process, we give a general construction of the kleisli extension of a monad to the category of v-relations.

Various mechanisms for authenticating users of computer-based information systems have been proposed. These include traditional, user-selected passwords, system-generated passwords, passphrases, cognitive passwords and associative passwords. While the mechanisms employed in primary passwords are determined by the operating systems' manufacturers, system designers can select any password mechani...
