Abstract: Highlights•Discovery of dominant balances of two or more equation terms yields insights.•Dominant balances often arise in nonlinear dynamical systems.•Automated dominant balance discovery requires hyperparameter tuning.•We present a robust objective criterion for dominant balance identification.•Objective hyper-parameter tuning enables automated dominant balance discovery.
