Pred np.argmax predict
WebOct 13, 2024 · In the newest version of Tensorflow, the predict_classes function has been deprecated (there was a warning in previous versions about this). The new syntax is as follows: Y_pred = np.argmax(model.predict(X_test),axis=1) Webcm = confusion_matrix(y_true=test_batches.classes, y_pred=np.argmax(predictions, axis=-1)) To the confusion matrix, we pass the true labels of the test set, along with the predicted labels for the test set from the model. Note, we can access the unshuffled …

WebAug 9, 2024 · 1. The code you've mentioned sorts an array in ascending order and returns arguments (the labels) for the first k. As you want to predict one class, you need to evaluate, how each of classes is close to the considered point. Distance of j class could be computed as a sum of 1/distance (x_i)**2 for all points with the label j, which are laying ...
