AdityaSavara / PEUQSE

Parameter estimation for complex physical problems often suffers from finding ‘solutions’ that are not physically realistic. The PEUQSE software provides tools for finding physically realistic parameter estimates, graphs of the parameter estimate positions within parameter space, and plots of the final simulation results.

Change Astroidal to Random in higher dimensions #335

Open AdityaSavara opened 1 year ago

AdityaSavara commented 1 year ago

In higher dimensions, the odds of overlapping points are low. More importantly, I found that the higher dimension sobol sampling has distinct patterns (see attachment). Heat_Scatter.zip

I think it should switch to totally random when dimension is greater than 3.

Evidently, Sobol indices in SciPy have had an upgrade at some point, and the options in it could be investigated. https://github.com/SALib/SALib/issues/463
