Function to optimize the projection index
This function provides an alternative way to optimize the projection index, by moving along a geodesic path.
The Starting Projection for the optimization.
The Projection Index function. Typically generated by a
call to the
The number of new bases to try at every stage of the
optimization. Needs to be an array of the same length as
The number of new bases desired. Actual number generated may be lesser if optimization stalls.
This function provides an alternative way to optimize the projection index. It moves the index along geodesic paths between randomly generated nearby matrices, in hopes of uncovering peaks of the index function. By experience, one can say that it can often reveal structure missed by Simulated Annealing optimization.
A list of basis matrices, of length
bases or shorter (if
the optimization stalls).
