    visualize a decision tree in 4 ways with scikit-learn and

    Jun 22, 2020 · A Decision Tree is a supervised algorithm used in machine learning. It is using a binary tree graph (each node has two children) to assign for each data sample a target value. The target values are presented in the tree leaves. To reach to the leaf, the sample is propagated through nodes, starting at the root node. In each node a decision is made, to which descendant node it should go

Once we’re done with the above steps, we will use different algorithms as classifiers, make predictions, print the ‘Classification Report’, the ‘Confusion Matrix’, and the ‘Accuracy Score’. The Classification Report will give us the precision, recall, f1-score, support, and accuracy, whereas the Confusion Matrix

    To add to @akilat90's update about sklearn.metrics.plot_confusion_matrix: You can use the ConfusionMatrixDisplay class within sklearn.metrics directly and bypass the need to pass a classifier to plot_confusion_matrix. It also has the display_labels argument, which allows you to specify the labels displayed in the plot as desired

    how to interpret classification report of scikit-learn?

    The classification report is about key metrics in a classification problem. You'll have precision, recall, f1-score and support for each class you're trying to find. The recall means "how many of this class you find over the whole number of element of this class" The precision will be "how many are correctly classified among that class"
