Import confusion matrix in python
WitrynaThe following code snippet shows how to create a confusion matrix and calculate some important metrics using a Python library called scikit-learn (also known as sklearn ): # Importing the dependancies from sklearn import metrics # Predicted values y_pred = ["a", "b", "c", "a", "b"] # Actual values y_act = ["a", "b", "c", "c", "a"] WitrynaTo help you get started, we’ve selected a few matplotlib examples, based on popular ways it is used in public projects.
