Web22 gen 2024 · 1. Suppose you want to create a confusion matrix of predictions and real values from dataset called dtm, where your target variable is called type. First of all you have to predict the value according to the model using: prediction <- predict (model, dtm) Then you can create the confusion matrix with the code: Web26 ott 2024 · A Support Vector Machine (SVM) is a discriminative classifier formally defined by a separating hyperplane. In other words, given labeled training data (supervised learning), the algorithm outputs an optimal hyperplane that categorizes new examples. The most important question that arises while using SVM is how to decide the right hyperplane.
