denotes the dynamic shear in the product, n would be the flow sample index, dimensionless; and K could be the regularity factor with the drilling fluid, Pa·sn. K-fold cross-validation is particularly beneficial for preventing overfitting, since it enables us to comprehensively evaluate a design’s predictive functionality on different parts https://medium.com/@vertechs/revolutionizing-the-depths-how-vertechs-is-redefining-drilling-fluids-for-safer-smarter-oilfield-68892e0971a0
