{"pk":25620,"title":"Partitioning the Firing Patterns of Spike Trains by\nCommunity Modularity","subtitle":null,"abstract":"The traditional clustering method utilized to partition\nneuronal firing patterns, including K-means and FCM\nalgorithm, require specification of clusters numbers as priori\nknowledge. A new approach to analyze groups of firing\npatterns of neuronal spike trains based on community\nstructure partitioning analysis and modularity function Q is\nexamined in this study. This approach is able to automatically\nidentify the optimal number of groups in neuronal firing\npatterns, realizing the true unsupervised analysis, and identify\ngroups of neurons with similar firing patterns. The method\nwas tested on a surrogate data set and a testing data set with\nfiring patterns known in advance. The method was also\napplied to multi-electrode recording spike trains with\npreviously unknown patterns. Results indicate this method\ncan effectively self-determine number of pattern groups and\nlocate firing patterns of neuronal populations based on\ncommunity modularity Q.","language":"eng","license":{"name":"","short_name":"","text":null,"url":""},"keywords":[{"word":"Community structure; Modularity; Clustering;\nNeuronal firing pattern"}],"section":"Papers","is_remote":true,"remote_url":"https://escholarship.org/uc/item/0v86d6c8","frozenauthors":[{"first_name":"Hu","middle_name":"","last_name":"Lu","name_suffix":"","institution":"Fudan University","department":""},{"first_name":"Xing","middle_name":"Hao","last_name":"Huang","name_suffix":"","institution":"Jiangsu University","department":""},{"first_name":"Yu","middle_name":"Qing","last_name":"Song","name_suffix":"","institution":"Jiangsu University","department":""},{"first_name":"Hui","middle_name":"","last_name":"Wei","name_suffix":"","institution":"Fudan University","department":""}],"date_submitted":null,"date_accepted":null,"date_published":"2015-01-01T18:00:00Z","render_galley":null,"galleys":[{"label":"PDF","type":"pdf","path":"https://journalpub.escholarship.org/cognitivesciencesociety/article/25620/galley/15244/download/"}]}
