"NeuralNetwork" (Machine Learning Method)

Details & Suboptions

  • A neural network consists of stacked layers, each performing a simple computation. Information is processed layer by layer from the input layer to the output layer. The neural network is trained to minimize a loss function on the training set using gradient descent.
  • The following options can be given:
  • MaxTrainingRounds Automaticmaximum number of iterations over the dataset
    "NetworkDepth" Automaticthe depth of the network
  • The option "NetworkDepth" controls the capacity of the network. A deeper network will be able to fit more complex patterns but will be more prone to overfitting.
  • The option MaxTrainingRounds can be used to speed up the training but also as a regularization parameter: setting a lower value can prevent overfitting.
