Building a Deep Feedforward Neural Network

In this chapter, we will cover the following recipes:

  • Training a vanilla neural network
  • Scaling the input dataset
  • Impact of training when the majority of inputs are greater than zero
  • Impact of batch size on model accuracy
  • Building a deep neural network to improve network accuracy
  • Varying the learning rate to improve network accuracy
  • Varying the loss optimizer to improve network accuracy
  • Understanding the scenario of overfitting
  • Speeding up the training process using batch normalization

In the previous chapter, we looked at the basics of the function of a neural network. We also learned that there are various hyperparameters that impact the accuracy of a neural network. In this chapter, we will get into the details of the functions of the various hyperparameters within a neural network.
