Sloppy-Model Universality Class and the Vandermonde Matrix
Sloppy-Model Universality Class and the Vandermonde Matrix
In a variety of contexts, physicists study complex, nonlinear models with many unknown or tunable parameters to explain experimental data. We explain why such systems so often are sloppy: the system behavior depends only on a few "stiff" combinations of the parameters and is unchanged as other "sloppy" parameter combinations …
