<DIV>Dear Friends,</DIV> <DIV> </DIV> <DIV> <DIV>I was going read about Infomax algorithm, I know that runica() function in EEGLAB has implemented an infomax algorithm with the natural gradient of Amari, but I was reading an article about that, and it seems that natural gradient doesn't have implemented.</DIV> <DIV> </DIV> <DIV>The article is "<STRONG>Artifact Extraction from EEG Data using Independent Component Analysis"</STRONG></DIV> <DIV><STRONG></STRONG> </DIV> <DIV><FONT face=TimesNewRomanPSMT color=#231f20 size=4> <DIV align=left>Shadab Mozaffar</DIV> <DIV align=left>David W. Petr</DIV></FONT></DIV></DIV> <DIV> </DIV> <DIV>But, they show that their learning rules are the same that you use in runica() with natural gradient, but they use an stochastic gradient.</DIV> <DIV> </DIV> <DIV>Can you see the pictures attaches please, They show a diferent form to have the same learing rule, but without use natural gradient.</DIV>
<DIV> </DIV> <DIV>Thanks in advanced</DIV> <DIV> </DIV> <DIV>Ary</DIV><p>
