Our approach is adapted to the needs of functional brain imaging rather than EEG-based brain-computer interface (BCI). This choice leads to a different set of requirements, in particular to the demand for more robust inference methods and more sophisticated model validation techniques. We approach the problem from a machine learning perspective, by constructing a classifier from a set of labeled signal examples. We propose a framework that focuses on temporal evolution of regularized classifiers, with cross-validation for optimal regularization parameter at each time frame. We demonstrate the inference obtained by this method on MEG data recorded from 10 subjects in a simple visual classification experiment, and provide comparison to the classical nonregularized approach.<\/jats:p>","DOI":"10.1155\/2007\/52609","type":"journal-article","created":{"date-parts":[[2007,9,5]],"date-time":"2007-09-05T08:07:45Z","timestamp":1188979665000},"page":"1-8","source":"Crossref","is-referenced-by-count":4,"title":["Inferring Functional Brain States Using Temporal Evolution of Regularized Classifiers"],"prefix":"10.1155","volume":"2007","author":[{"given":"Andrey","family":"Zhdanov","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Talma","family":"Hendler","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leslie","family":"Ungerleider","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nathan","family":"Intrator","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"98","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.bb.02.060173.001105"},{"issue":"5","key":"2","doi-asserted-by":"crossref","first-page":"633","DOI":"10.1109\/PROC.1977.10542","volume":"65","year":"1977","journal-title":"Proceedings of the IEEE"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1109\/86.847808"},{"key":"4","doi-asserted-by":"publisher","DOI":"10.1109\/5.939829"},{"key":"5","doi-asserted-by":"publisher","DOI":"10.1109\/TNSRE.2003.814456"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1109\/TBME.2004.827086"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.0403504101"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1109\/86.847812"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1109\/86.895946"},{"key":"10","doi-asserted-by":"publisher","DOI":"10.1109\/TBME.2005.851521"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1016\/S0893-6080(98)00060-4"},{"key":"13","doi-asserted-by":"publisher","DOI":"10.1109\/TNSRE.2003.814484"},{"key":"14","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.ph.55.030193.002025"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1016\/0013-4694(77)90235-8"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1016\/S0304-3940(00)01471-3"},{"key":"18","doi-asserted-by":"publisher","DOI":"10.1016\/S1053-8119(03)00049-1"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1038\/nn1444"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1016\/j.tics.2006.07.005"},{"key":"21","doi-asserted-by":"publisher","DOI":"10.1126\/science.1117645"},{"key":"22","volume-title":"Pictures of Facial Affect","year":"1976"},{"key":"23","volume-title":"The Karolinska Directed Emotional Faces (KDEF)","year":"1998"},{"key":"24","doi-asserted-by":"crossref","first-page":"179","DOI":"10.1111\/j.1469-1809.1936.tb02137.x","volume":"7","year":"1936","journal-title":"Annals of Eugenics"},{"key":"25","doi-asserted-by":"publisher","DOI":"10.2307\/2289860"},{"key":"27","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.94.7.3408"},{"issue":"6","key":"28","doi-asserted-by":"crossref","first-page":"551","DOI":"10.1162\/jocn.1996.8.6.551","volume":"8","year":"1996","journal-title":"Journal of Cognitive Neuroscience"},{"key":"29","doi-asserted-by":"publisher","DOI":"10.1016\/S0010-0277(01)00162-7"}],"container-title":["Computational Intelligence and Neuroscience"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/cin\/2007\/052609.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/cin\/2007\/052609.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2017,6,17]],"date-time":"2017-06-17T22:35:29Z","timestamp":1497738929000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.hindawi.com\/journals\/cin\/2007\/052609\/abs\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2007]]},"references-count":26,"alternative-id":["052609","52609"],"URL":"https:\/\/doi.org\/10.1155\/2007\/52609","relation":{},"ISSN":["1687-5265","1687-5273"],"issn-type":[{"value":"1687-5265","type":"print"},{"value":"1687-5273","type":"electronic"}],"subject":[],"published":{"date-parts":[[2007]]}}}
