<div dir="ltr"><div class="gmail_extra"><div class="gmail_quote"><div>Dear Robert and list,</div><div><br></div><div>If I remember correctly, one of the critical issue was how phase changes in 'channel data' after removing independent components. Let me focus on this point only.</div><div><br></div><div>1. To show my rebuttal and mathematical proof, I prepared a wiki page. In this page. I described how a phase is split/synthesized before and after linear decomposition. Note that this applies to any linear decomposition and not specific to ICA. In doing so, made it nice and educational to show my respect to Arno's effort. Hopefully this mathematical clarification helps.</div><div><br></div><div> <a href="https://sccn.ucsd.edu/wiki/How_phase_is_calculated_in_linear_decomposition">https://sccn.ucsd.edu/wiki/How_phase_is_calculated_in_linear_decomposition</a></div><div><br></div><div>Robert, if you do not agree,<b> please show the right process in a form of math</b>.</div><div><br></div><div>2. Apart from this scientific/mathematical dispute, I insist that one should not use the word 'distortion' in this context because it includes subjective judgement.</div><div><br></div><div>Makoto</div><div><br></div><div><br></div><div><br></div></div>-- <br><div class="gmail_signature"><div dir="ltr">Makoto Miyakoshi<br>Swartz Center for Computational Neuroscience<br>Institute for Neural Computation, University of California San Diego<br></div></div>
