You can optimize Chainer hyperparameters, such as the number of layers and the number of hidden nodes in each layer, in three steps: Wrap model training with an objective function and return accuracy.

Using functions to perform repetitive tasks is an excellent way to create code reuse. This is an important part of modern object-oriented programming principles.
