Knn Accuracy Formula at James Raybon blog

Knn Accuracy Formula. the simplest way to evaluate this model is by using accuracy. return the mean accuracy on the given test data and labels. We check the predictions against the actual values in the test set and count up how many. another option is to calculate the confusion matrix, which tells you the accuracy of both classes and the alpha. train_score = knn.score(train_x,train_y) knn_r_acc.append((i, test_score ,train_score)) df = pd.dataframe(knn_r_acc, columns=['k','test score','train score']) print(df) the above code will run knn for various values of k (from 1 to 16) and store the train and test scores in a dataframe. The better that metric reflects label.
