It works best when we are dealing with mutually exclusive output. Let us take an example of predicting whether a patient will visit the hospital in future.
WebSoftmax Regression (synonyms: Multinomial Logistic, Maximum Entropy Classifier, or just Multi-class Logistic Regression) is a generalization of logistic regression that we can use for multi-class classification (under the assumption that the classes are mutually exclusive). In contrast, we use the (standard) Logistic Regression model in binary ... WebThe first is Multiclass Softmax, which we use both because it is a softmax-smoothed version of the Multiclass Perceptron and because it is the natural generalization of the two class version seen in e.g., Section 6.4.3. To see this more easily let us smooth the formulation of the Multiclass Perceptron given in equation (6), replacing the $\text{max}$ …
