#include <IMP/isd/GaussianEMRestraint.h>
Inheritance diagram for IMP::isd::GaussianEMRestraint:Creates a restraint between two Gaussian Mixture Models, "model" and "density".
This restrains two sets of GMMs with a density overlap function. The function is correlation of the two GMMs \(f_M\) and \(f_D\):
\[ \frac{2\int{f_M(x)f_D(x)dx}}{\int{f_M^2(x)+f_D^2(x)dx}} \]
Where the integral is the "overlap function" given by:
\[ ov(f_M,f_D) = \sum_{i=1}^{N_M} \sum_{j=1}^{N_D} \frac{1}{(2 \pi)^{3/2}|\Sigma_{Mi}+\Sigma_{Dj}|^{1/2}}\exp\left [-\frac{1}{2}(\boldsymbol\mu_{Mi} - \boldsymbol\mu_{Dj})^\top (\Sigma_{Mi}+\Sigma_{Dj})^{-1} (\boldsymbol\mu_{Mi} - \boldsymbol \mu_{Dj})\right ] \]
