question about random seed about amica HOT 5 CLOSED

Hi, There is a keyword 'fix_init' which you can set to 1 and it should produce the same output. Use the keyword in runamica15() in matlab or in the .param file if using binary only. Best, Jason

The starting point should not be that different so I’m not sure why it is working very differently, except that maybe with the fixed starting point it takes many more iterations. If the results are similar from two datasets, you may be looking at the sphering components near the starting point, which are similar for different datasets. If you increase max_iter to 10,000 it may converge to the non-fixed starting point solution.

As you had guided, I tested amICA after enabled 'fix_init', then can check returns the same results by every run. But weird thing is that all components are quite different from before enabled 'fix_init'. And we tested with another time-series data, all components are very similar with the result of the first time-series data, even if those two time-series data looks like different. It doesn't seems to amICA analyze components of time-series well, if not using random function. Could you explain me if there are any restrictions of enabling 'fix_init' ?
