This work presents a comparative study between two contrasted ROM approaches: Intrusive against Non-Intrusive techniques. To this aim, a model-based projection method and a machine-learning based system are presented and benchmarked using nonlinear dynamical test cases. Followingly, we perform a thorough performance analysis to highlight the benefits of each approach.
