This hands-on example will guide you through the process, emphasizing the core concepts of data loading, model definition, and training.

Defining the Model

The first step in building a Flax application involves defining the model architecture. This involves specifying the layers and their connections within the neural network. A simple example using a linear layer demonstrates this process.“`pythonimport jaximport flax.linen as nnclass MyModel(nn.Module): features: int @nn.compact def __call__(self, x): x = nn.Dense(self.features)(x) return x“`This code defines a class `MyModel` that inherits from `flax.linen.Module`.

The `@nn.compact` decorator ensures that parameters are properly tracked. The `__call__` method defines the model’s forward pass, applying a dense layer (`nn.Dense`) to the input `x`. The `features` parameter allows customization of the output dimension of the dense layer.

Preparing Input Data

Preparing input data is crucial for model training. This involves transforming raw data into a suitable format for the model.“`pythonimport jax.numpy as jnp# Example input datainput_data = jnp.array([[1.0, 2.0, 3.0], [4.0, 5.0, 6.0]])“`This example demonstrates a simple input dataset, represented as a NumPy array. This array can be loaded from various sources, such as CSV files or databases, depending on the specific application.

Instantiating and Running the Model

This section explains the process of instantiating the model and running it on the input data. This step utilizes the `MyModel` class created in the previous section.“`python# Instantiate the model with 2 output featuresmodel = MyModel(features=2)# Apply the model to the input dataoutput = model.apply(None, input_data)print(output)“`The example creates an instance of the `MyModel` class, setting the number of output features to 2.
