WebAug 5, 2024 · Keras models can be used to detect trends and make predictions, using the model.predict () class and it’s variant, reconstructed_model.predict (): model.predict () – A model can be created and fitted with trained data, and used to make a prediction: yhat = model.predict (X) The predict_classes method is only available for the Sequential class (which is the class of your first model) but not for the Model class (the class of your second model). With the Model class, you can use the predict method which will give you a vector of probabilities and then get the argmax of this vector (with np.argmax (y_pred1,axis=1) ).
