ABSTRACT In the present paper, an effort has been made to compare and analyze the performance for pattern recalling with conventional hebbian learning rule and with evolutionary algorithm in Hopfield Model of feedback Neural Networks. A set of ten objects has been considered as the pattern set. In the Hopfield type of neural networks of associative memory, the weighted code of input patterns pr...

This first ever functional magnetic resonance imaging (fMRI) analysis of charitable bequest decision-making found increased activation in the precuneus and lingual gyrus of the brain compared to charitable giving and volunteering decisions. Greater lingual gyrus activation was also associated with increased propensity to make a charitable bequest. Previous studies have shown that activation of ...

This paper addresses one aspect of human music cognition, which is the recollection of melodic sequences stored in short-term memory, and the manipulation of such items in working memory, by measuring spans of successfully recalled melodic sequences. In order to avoid long-term memory collaboration in this task, short-term memory measurements are made using randomly-generated melodic sequences,...

We present a mixed-signal implementation of a re-configurable polychronous spiking neural network capable of storing and recalling spatio-temporal patterns. The proposed neural network contains one neuron array and one axon array. Spike Timing Dependent Delay Plasticity is used to fine-tune delays and add dynamics to the network. In our mixed-signal implementation, the neurons and axons have be...

We explored the relation between individual differences in working memory (WM) and color constancy, the phenomenon of color perception that allows us to perceive the color of an object as relatively stable under changes in illumination. Successive color constancy (measured by first viewing a colored surface under a particular illumination and later recalling it under a new illumination) was bet...

Previous research has shown that spending money on others (prosocial spending) increases happiness. But, do the happiness gains depend on who the money is spent on? Sociologists have distinguished between strong ties with close friends and family and weak ties--relationships characterized by less frequent contact, lower emotional intensity, and limited intimacy. We randomly assigned participant...

This research investigates whether metacognitive experiences accompanying the retrieval of autobiographical memories influence judgments about others. Based on social projection research, we tested the hypothesis that ease-of-retrieval, affecting how the self is perceived, affects first impressions. In line with this prediction, Experiment 1 showed that participants asked to recall a few person...

In this paper, implementation of a genetic algorithm has been described to store and later, recall of some prototype patterns in Hopfield neural network associative memory. Various operators of genetic algorithm (mutation, cross-over, elitism etc) are used to evolve the population of optimal weight matrices for the purpose of storing the patterns and then recalling of the patterns with induced ...

We try to review the main current ideas and points of view on the running coupling constant in QCD. We begin by recalling briefly the classic analysis based on the Renormalization Group Equations with some emphasis on the exact solutions for a given number of loops, in comparison with the usual approximate expressions. We give particular attention to the problem of eliminating the unphysical La...

This paper reviews the performance of 10 previously reported patients who have deficits in recalling the names of people, but whose performance in recalling common names is relatively well preserved. An analysis of face naming ability in these 10 patients reveals that the proportion of faces that a patient can name is closely related to whether or not the patient has a retrieval problem that al...
