Learning theory based on ERM principle, especially promoted by VC theory provides some conditions on the hypothesis space to ensure generalization. However, several successful learning algorithms including regularization learning, SVM, bagging and boost are not strictly ERM. So, scientists are looking for new foundation of learning. Stability conditions are(More)
Ultrasonic quantitative shear-wave imaging methods have been developed over the last decade to estimate tissue elasticity by measuring the speed of propagating shear waves following acoustic radiation force excitation. This work discusses eight sources of uncertainty and bias arising from ultrasound system-dependent parameters in ultrasound shear-wave speed(More)
