I would like to know if somebody has an example on how to use the
Levenberg Marquart optimizer or specifically how to set up the cost
function. I haven't been able to find examples.
I'm trying to perform a re-weighted least squares minimization, the
levenberg Marquart might do it. Any help pointing in the right direction
will be very helpful.
Thank you in advance,
