[{"abstract":[{"text":"We propose a new algorithm for vector quantization, the Activity Equalization Vector quantization (AEV). It is based on the winner takes all rule with an additional supervision of the average node activities over a training interval and a subsequent re-positioning of those nodes with low average activities. The re-positioning is aimed to both an exploration of the data space and a better approximation of already discovered data clusters by an equalization of the node activities. We introduce a learning scheme for AEV which requires as previous knowledge about the data only their bounding box. Using an example of Martinetz et al. [1], AEV is compared with the Neural Gas, Frequency Sensitive Competitive Learning (FSCL) and other standard algorithms. It turns out to converge much faster and requires less computational effort.","lang":"eng"}],"year":"2001","intvolume":" 13","status":"public","isi":1,"date_submitted":"2011-06-15T19:45:42Z","type":"journal_article","date_created":"2010-04-28T13:03:21Z","issue":"1","publication_identifier":{"issn":["1370-4621"]},"department":[{"_id":"10038"},{"_id":"10066"}],"quality_controlled":"1","title":"Efficient vector quantization using the WTA-rule with activity equalization","author":[{"last_name":"Heidemann","full_name":"Heidemann, Gunther","first_name":"Gunther","autoren_ansetzung":["Heidemann, Gunther","Heidemann","Gunther Heidemann","Heidemann, G","Heidemann, G.","G Heidemann","G.
