Overall, nonlinear machine-learning algorithms demonstrated similar AUCs compared with linear algorithms. The Random Forest and Kernel Support Vector Machines algorithms achieved slightly greater AUCs in the validation cohort (0.954, 95% CI: 0.939-0.969; 0.954 95%CI: 0.939-0.969, respectively) than ...

— Page 175, Deep Learning, 2016. Because the rectified function is linear for half of the input domain and nonlinear for the other half, it is referred to as a piecewise linear function or a hinge function. However, the function remains very close to linear, in the sense that is a...

tidyfit is an R-package that facilitates and automates linear and nonlinear regression and classification modeling in a tidy environment. The package includes methods such as the Lasso, PLS, time-varying parameter or Bayesian model averaging regressions, and many more. The aim is threefold: Offer...
Fig. 1. DL-Reg’s intuition: Given a set of training data shown by black dots, (left) FW(X) represents a deep neural network, which uses its full capacity and learns a highly nonlinear function; (right) LR(X) determines a linear regression function that fits to the outputs of FW(X...
