In this paper, we propose a new energy function, which is nonnegative and attains zero values only at the desired memory patterns. An attractor network is designed based on the proposed energy function. It is shown that the desired memory patterns are stored as the stable equilibrium points of the attractor network. To retrieve a memory pattern, an initial stimulus input is presented to the network, and its states converge to one of stable equilibrium points. Consequently, the existence of the spurious points, that is, local maxima, saddle points, or other local minima which are undesired memory patterns, can be avoided. The simulation results show the effectiveness of the proposed method.<\/jats:p>","DOI":"10.1155\/2015\/191745","type":"journal-article","created":{"date-parts":[[2015,4,19]],"date-time":"2015-04-19T17:01:36Z","timestamp":1429462896000},"page":"1-7","source":"Crossref","is-referenced-by-count":4,"title":["Memory Dynamics in Attractor Networks"],"prefix":"10.1155","volume":"2015","author":[{"given":"Guoqi","family":"Li","sequence":"first","affiliation":[{"name":"Centre for Brain Inspired Computing Research (CBICR), Department of Precision Instrument, Tsinghua University, Beijing 100084, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kiruthika","family":"Ramanathan","sequence":"additional","affiliation":[{"name":"Department of Advanced Concepts and Nanotechnology (ACN), Data Storage Institute, A*STAR, 5 Engineer Drive 1, Singapore 117608"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ning","family":"Ning","sequence":"additional","affiliation":[{"name":"Department of Advanced Concepts and Nanotechnology (ACN), Data Storage Institute, A*STAR, 5 Engineer Drive 1, Singapore 117608"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Luping","family":"Shi","sequence":"additional","affiliation":[{"name":"Centre for Brain Inspired Computing Research (CBICR), Department of Precision Instrument, Tsinghua University, Beijing 100084, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Changyun","family":"Wen","sequence":"additional","affiliation":[{"name":"School of Electrical and Electronic Engineering, Nanyang Technological University, Singapore 639798"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1007\/s00339-011-6297-0"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1142\/s0129065713500196"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1103\/physreva.32.1007"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1162\/089976603321192086"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1126\/science.1112555"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1016\/j.neuron.2005.10.006"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1162\/neco.2010.07-09-1050"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1038\/335817a0"},{"issue":"5870","key":"9","first-page":"1640","volume":"319","year":"1999","journal-title":"Science"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.79.8.2554"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1007\/s10827-005-6558-z"},{"key":"12","doi-asserted-by":"publisher","DOI":"10.1103\/PhysRevLett.61.259"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1126\/science.1108905"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1109\/TNN.2004.841775"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1090\/S0002-9939-98-04500-6"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1016\/j.neunet.2008.06.005"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1038\/81444"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1016\/j.neunet.2003.11.007"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1162\/0899766054615644"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1162\/08997660151134325"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1109\/TSP.2011.2112355"}],"container-title":["Computational Intelligence and Neuroscience"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/cin\/2015\/191745.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cin\/2015\/191745.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cin\/2015\/191745.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2016,8,18]],"date-time":"2016-08-18T09:55:11Z","timestamp":1471514111000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/cin\/2015\/191745\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2015]]},"references-count":21,"alternative-id":["191745","191745"],"URL":"https:\/\/doi.org\/10.1155\/2015\/191745","relation":{},"ISSN":["1687-5265","1687-5273"],"issn-type":[{"type":"print","value":"1687-5265"},{"type":"electronic","value":"1687-5273"}],"subject":[],"published":{"date-parts":[[2015]]}}}
