Convolutional Neural Network

• ...

To-do list

• Use validation data for hyper parameter tuning
  • hyper paramters: epochs, mini-batch size, learning rate, momentum
• Plots for monitoring loss and accuracy over epochs
  • With data as arg ( options: training_data, validation_data, test_data )
• Regularization techniques: L1, L2, dropout
• Add optimizers: Adam, RMSProp
• CNN
• RBF NN
