Model development process in Keras
Building a neural network with Keras involves several straightforward steps designed to streamline the model development process.
Create a network
In Keras, the first step is defining the model architecture. Users can choose between two primary types: Sequential and Functional.
Assemble a network
Next, developers use the `model.compile()` method to configure the model’s loss function, optimizer, and metrics. This step sets the groundwork for effective training.
Adapt to the network
Using the `model.fit()` function, practitioners fit the model to their training data, allowing the network to learn from the provided examples.
Evaluate the network
Finally, Keras offers the `model.predict()` method, enabling users to assess model accuracy and generate predictions based on the tested data set.
