A model for neural representation of intervals of time
نویسندگان
چکیده
We put forward a model for neural representation of intervals of time. The model is comprised of ordinary recurrent neural networks. Assumptions speci"c to our model are the following two: membrane potential of each neuron is bistable; each neuron receives random noise input in addition to the recurrent input. Results of computer simulation show that the network activity triggered at an initial time continues for prolonged duration followed by an abrupt self-termination. This time course seems quite suitable for representation of intervals of time. Weber's law, a hallmark of human and animal interval timing, is also reproduced. 2000 Elsevier Science B.V.

Neuron Mathematical Model Representation of Neural Tensor Network for RDF Knowledge Base Completion
In this paper, a state-of-the-art neuron mathematical model of neural tensor network (NTN) is proposed to RDF knowledge base completion problem. One of the difficulties with the parameter of the network is that representation of its neuron mathematical model is not possible. For this reason, a new representation of this network is suggested that solves this difficulty. In the representation, th...

Text clustering and classification are two main tasks of text mining. Feature selection plays the key role in the quality of the clustering and classification results. Although word-based features such as term frequency-inverse document frequency (TF-IDF) vectors have been widely used in different applications, their shortcoming in capturing semantic concepts of text motivated researches to use...

Earthquakes are one of the most destructive natural phenomena which consist of rapid vibrations of rock near the earth’s surface. Because of their unpredictable occurrence and enormous capacity of destruction, they have brought fear to mankind since ancient times. Usually the earthquake acceleration is noted from the equipment in crisp or exact form. But in actual practice those data may not be...
