A colourcoding scheme is used to illustrate the evaluation of the posteriorprobabilities in the E-step of the EM algorithm.<p><h2>See Also</h2><CODE><a href="demgmm2.htm">demgmm2</a></CODE>, <CODE><a href="demgmm3.htm">demgmm3</a></CODE>, <CODE><a href="demgmm4.htm">demgmm4</a></CODE>, <CODE><a href="gmm.htm">gmm</a></CODE>, <CODE><a href="gmmem.htm">gmmem</a></CODE>, <CODE><a href="gmmpost.htm">gmmpost</a></CODE><hr><b>Pages:</b><a href="index.htm">Index</a><hr><p>Copyright (c) Ian T Nabney (1996-9)</body></html>⌨️ 快捷键说明
