Webordinal hyperplane loss, ordinal classification, ordinal regression, deep learning, loss function, machine learning . I. I. NTRODUCTION. The problem of ordinal classification occurs in a large and growing number of areas. Some of the most common sources and applications of ordinal data are: • Ratings scales (e.g. Likert scales), like customer In geometry, a hyperplane is a subspace whose dimension is one less than that of its ambient space. For example, if a space is 3-dimensional then its hyperplanes are the 2-dimensional planes, while if the space is 2-dimensional, its hyperplanes are the 1-dimensional lines. This notion can be used in any general space in which the concept of the dimension of a subspace is defined. cheaters recall lolWebloss {‘hinge’, ‘squared_hinge’}, default=’squared_hinge’ Specifies the loss function. ‘hinge’ is the standard SVM loss (used e.g. by the SVC class) while ‘squared_hinge’ is the … cheaters registry
