Python svm multiclass
WebFeb 11, 2024 · In this notebook, a Multiclass Support Vector Machine (SVM) will be implemented. For this exercise, a linear SVM will be used. Linear classifiers differ from k-NN in a sense that instead of memorizing the whole training data every run, the classifier creates a “hypothesis” (called a parameter ), and adjusts it accordingly during training time. WebMar 15, 2024 · The dependent variable (species) contains three possible values: Setoso, Versicolor, and Virginica. This is a classic case of multi-class classification problem, as the number of species to be predicted is more than two. We will use the inbuilt Random Forest Classifier function in the Scikit-learn Library to predict the species.
