01/04/22:
- 12:01 Changeset [18179] by
-
#3136: improved parameter optimization for NMSEConstraintsEvaluator. Use LM directly instead of lsfit to improve efficiency by using vectorized callbacks.
- 10:43 Changeset [18178] by
-
#3136 copied code with minor modifications from ParameterOptimizationEvaluator into the NMSEConstraintsEvaluator because the code in ParameterOptimizationEvaluator uses R² internally and is incompatible to the NMSEEvaluator.
