Exploring model architectures and hyperparameters with Keras

Hyperparameter tuning is an important part of building deep neural networks. In this post we'll explore the two distinct kinds of hyperparameters to tune: Model hyperparameters and Optimization hyperparameters.

Model hyperparameters relate to the overall architecture of our model. These hyperparameters include the number of hidden layers in our model …

Batch Normalization in deep neural networks.

Batch Normalization is a straightforward way for optimizing the training of deep neural networks. It is based on the idea that inputs to all layers of a neural network should be whitened - i.e. linearly transformed to have zero mean and unit variance, before being fed into the activation function …
