Is linear regression discriminative

Discriminative models, also referred to as conditional models, are a class of logistical models used for classification or regression. They distinguish decision boundaries through observed data, such as pass/fail, win/lose, alive/dead or healthy/sick. Typical discriminative models include logistic regression (LR), … Zobacz więcej The following approach is based on the assumption that it is given the training data-set $${\displaystyle D=\{(x_{i};y_{i}) i\leq N\in \mathbb {Z} \}}$$, where $${\displaystyle y_{i}}$$is the corresponding … Zobacz więcej Examples of discriminative models include: • Logistic regression, a type of generalized linear regression used … Zobacz więcej Contrast in approaches Let's say we are given the $${\displaystyle m}$$ class labels (classification) and A generative … Zobacz więcej Since both advantages and disadvantages present on the two way of modeling, combining both approaches will be a good modeling in practice. For example, in Marras' article A Joint Discriminative Generative Model for Deformable Model Construction … Zobacz więcej • Mathematics portal • Generative model Zobacz więcej Linear discriminant analysis (LDA), normal discriminant analysis (NDA), or discriminant function analysis is a generalization of Fisher's linear discriminant, a method used in statistics and other fields, to find a linear combination of features that characterizes or separates two or more classes of objects or events. The resulting combination may be used as a linear classifier, or, more commonly, for dimensionality reduction before later classification.
