WebLinear models are supervised learning algorithms used for solving either classification or regression problems. For input, you give the model labeled examples ( x , y ). x is a high-dimensional vector and y is a numeric label. For binary classification problems, the label must be either 0 or 1. For multiclass classification problems, the labels must be from 0 to WebFor one-class or binary classification, and if you have an Optimization Toolbox license, you can choose to use quadprog (Optimization Toolbox) to solve the one-norm problem. quadprog uses a good deal of memory, but solves quadratic programs to a high degree of precision.
