Preparing a model for tuning

Let's tune the hyperparameters of a binary classification model that does well classifying the breast cancer dataset.

You've seen that the first step to turn a model into a sklearn estimator is to build a function that creates it. The definition of this function is important since hyperparameter tuning is carried out by varying the arguments your function receives.

Build a simple create_model() function that receives both a learning rate and an activation function as arguments. The Adam optimizer has been imported as an object from tensorflow.keras.optimizers so that you can also change its learning rate parameter.

  • Set the learning rate of the Adam optimizer object to the one passed in the arguments.
  • Set the hidden layers activations to the one passed in the arguments.
  • Pass the optimizer and the binary cross-entropy loss to the .compile() method.
