Hinge joint best examples of ginglymoid joints are the Interphalangeal joints of the hand and those of the foot and the joint between the humerus and ulna. The knee joints and ankle joints are less typical, as they allow a slight degree of rotation or of side-to-side movement in certain positions of the limb. The knee is the largest hinge joint in the human body. Hinge and pivot joints are both types of synovial joint. A hinge joint can be considered a modified sellar/saddle joint, with reduced movement. Other objects that work like hinged joints are door hinges, closet doors, and dog
Hinge loss the right class) and formula_5, the hinge loss formula_6, but when they have opposite signs, formula_7 increases linearly with (one-sided error), and similarly if formula_8, even if it has the same sign (correct prediction, but not by enough margin). While binary SVMs are commonly extended to multiclass classification in a one-vs.-all or one-vs.-one fashion, it is also possible to extend the hinge loss itself for such an end. Several different variations of multiclass hinge loss have been proposed. For example, Crammer and Singer defined it for a linear classifier as Where formula_10 the target label, formula_11 and formula_12 the model
