Solution
It seems like you haven't provided a specific question related to the statement about training a deeper network. However, I can provide a general response based on the information given.
Training a deeper network, which means adding more layers to the neural network, does indeed allow the network to fit more complex functions. This is because each layer in a neural network learns to recognize different features of the input data. The more layers there are, the more complex the features the network can recognize.
For example, in a network trained to recognize images, the first layer might learn to recognize simple shapes, the second layer could recognize combinations of these shapes, and so on. By the time you get to the final layer, the network can recognize very complex features.
As a result, a deeper network can often achieve lower training error, because it can fit the training data more closely. However, this doesn't always mean that the network will perform better on new, unseen data. If a network is too deep and complex, it can overfit the training data, meaning it learns the training data so well that it performs poorly on new data. This is a common problem in machine learning known as overfitting.
So, while a deeper network can reduce training error, it's also important to ensure that the network generalizes well to new data. This can be achieved through techniques like regularization and cross-validation.
