Unfortunately, network structural inference is time consuming and there is an increasing need to infer the structure of ever-larger networks. This article presents DSEM, a novel extension of the SEM algorithm. DSEM increases the efficiency of structural inference by using the time-expensive calculations required in each SEM iteration more eff… text/html 2013-03-17T12:50:47+01:00 Christo Fogelberg http://syntilect.com/cgf/pubs:index?rev=1363524647&do=diff DPhil thesis, peer reviewed publications, technical reports, position papers etc., in reverse chronological order. 2013 * Dense Structural Expectation Maximisation with Parallelisation for Efficient Large-Network Structural Inference (Fogelberg, Palade) text/html 2012-11-08T04:41:55+01:00 Christo Fogelberg http://syntilect.com/cgf/epistles:021?rev=1352349715&do=diff [This email is an update.
