# mu prediction for new matrix
# update_params
# get_optim_functions: return optim.func, optim.grad, optim.fngr
# param_optim_lower - lower bound of params
# param_optim_upper - upper
# param_optim_start - current param values
# param_optim_start0 - some central param values that can be used for optimization restarts
# param_optim_jitter - how to jitter params in optimization
