Nettet15. aug. 2024 · Linear Discriminant Analysis does address each of these points and is the go-to linear method for multi-class classification problems. Even with binary-classification problems, it is a good idea to try both logistic regression and linear discriminant analysis. Representation of LDA Models. The representation of LDA is … NettetIn the case of a linear kernel, the attributes coef_ and intercept_ have the shape (n_classes * (n_classes-1) / 2, n_features) and (n_classes * (n_classes-1) / 2) respectively. This is similar to the layout for LinearSVC described above, with each row now corresponding to a binary classifier.

Nettet8. apr. 2024 · For binary classification, we can choose a single neuron output passed through sigmoid, and then set a threshold to choose the class, or use two neuron output and then perform a softmax. In either of the cases, thresholding is possible.It is rather easy to plot a ROC curve with single neuron output, as you'll have to threshold over one value.
