Chapter 8: Project: Text Generation with Autoregressive Models

8.3 Training the Autoregressive Model

Once our autoregressive model has been created, the next step is to train it using our preprocessed data. The training process involves showing the model the input sequences and the corresponding target sequences, and adjusting the model's weights based on the error of its predictions.

Here's how we can train the model in Python:

def train_model(model, X, y, batch_size, num_epochs):
    model.fit(X, y, batch_size=batch_size, epochs=num_epochs, verbose=1) 

In the above function:

  • model is the autoregressive model created in the previous step.
  • X is the array of input sequences.
  • y is the array of target sequences.
  • batch_size specifies the number of samples per gradient update.
  • num_epochs is the number of epochs to train the model. An epoch is an iteration over the entire x and y data provided.

The fit function trains the model for a fixed number of epochs (iterations on a dataset). The verbose argument is set to 1, meaning that it will display a progress bar during training.

The batch size and number of epochs can be adjusted based on the computational resources available and how long you're willing to wait for training to complete. You might also need to experiment with different values to see what gives the best results. 

In practice, you would split your data into a training set and a validation set. You would train the model on the training set and evaluate its performance on the validation set at the end of each epoch. You would also use techniques such as early stopping to prevent overfitting.

Now that we have trained our model, we can move to the next step: generating text. This is the fun part, where we see the results of our hard work!
