Data-centric methods leverage conventional ML techniques to uncover relationships within specific datasets, demonstrating success in rheological properties prediction, material characterization, properties optimization, and accelerated numerical simulations. Physics-informed machine learning combines physical laws and domain knowledge with data to produce generalizable and physically consistent predictions, proving effective in solving rheological differential equations, utilizing multi-fidelity datasets to enhance predictions, and constitutive modeling. The paper also discusses the limitations of these approaches and the ongoing efforts to address them. Looking ahead, this article emphasizes the need for explainable ML techniques to enhance transparency and trust, improved tools for uncertainty quantification.

These developments make NFAs pivotal materials in advancing OSC technologies and they represent a promising alternative.
