Web10 Jan 2024 · The Keras functional API is a way to create models that are more flexible than the tf.keras.Sequential API. The functional API can handle models with non-linear topology, shared layers, and even multiple inputs or outputs. The main idea is that a deep learning model is usually a directed acyclic graph (DAG) of layers. Web25 Mar 2024 · Step 1) Create the train and test. First of all, you convert the series into a numpy array; then you define the windows (i.e., the number of time the network will learn from), the number of input, output and the size of the train set as shown in the TensorFlow RNN example below.
