WebUsing this function, we can see that since our data is categorical in nature, Keras has assigned the cat and dog classes these one-hot encoded vectors as its labels. imgs, labels = next (train_batches) plots (imgs, titles=labels) For example, a cat is not referred to as “cat” but instead as [ 0, 1]. Dog is referred to as [ 1, 0] . Web5 aug. 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)
