Finally we note that we may dispense with the probabilistic underpinnings of the product of experts and derive the same algorithm as a minimisation of mean squared error between the prototypes and the data. This leads us to suggest a new algorithm which incorporates local and global information in the clustering. Both ot the new algorithms achieve better results than the standard Self-Organizing Map. <\/jats:p>","DOI":"10.1142\/s0129065708001749","type":"journal-article","created":{"date-parts":[[2009,1,14]],"date-time":"2009-01-14T10:00:13Z","timestamp":1231927213000},"page":"481-489","source":"Crossref","is-referenced-by-count":11,"title":["TOPOLOGICAL MAPPINGS OF VIDEO AND AUDIO DATA"],"prefix":"10.1142","volume":"18","author":[{"given":"COLIN","family":"FYFE","sequence":"first","affiliation":[{"name":"Applied Computational Intelligence Research Unit, The University of The West of Scotland, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"WESAM","family":"BARBAKH","sequence":"additional","affiliation":[{"name":"Applied Computational Intelligence Research Unit, The University of The West of Scotland, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"WEI CHUAN","family":"OOI","sequence":"additional","affiliation":[{"name":"Department of Electronics and Computer Engineering, Korea University, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"HANSEOK","family":"KO","sequence":"additional","affiliation":[{"name":"Department of Electronics and Computer Engineering, Korea University, Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"219","published-online":{"date-parts":[[2011,11,21]]},"reference":[{"key":"rf1","author":"Bishop C.
