Java: Data Science Made Easy

Saving and retrieving the model

We can also save and retrieve a model for later use. To save the model, build the model and then use the SerializationHelper class' static method write, as shown in the following code snippet. The first argument is the name of the file to hold the model:

SerializationHelper.write("mlpModel", mlp); 

To retrieve the model, use the corresponding read method as shown here:

mlp = (MultilayerPerceptron)SerializationHelper.read("mlpModel"); 

Next, we will learn how to use another useful neural network approach, SOMs.
