Tutorial 3 LIU Tengfei 2/27/2009

Contents Filters Configuration of parameters Momentum

Filter(1) Example: remove attributes

Filter(2)

Filter(3)

Filter(4)

Configuration of parameters Example: Configure parameters of ANN classifier. Please refer to the “Example_2”.

Momentum(1)

Momentum(2)

Momentum(3) Backpropagation is a widely uesd algorithm, many variations have been developed. Note: 0 < a < 1 MomentumMomentum term

Momentum(4) 1.Keeping the ball rolling through local minima in the error surface; 2.Speeding up training
