Implementing an Incremental (online) Training Algorithm
for Density Neural Networks
Design and implement an incremental backpropagation algorithm for training density neural networks
(DNN). DNN networks compute not only the mean of the target distribution, but also the variance with a
second output node. That is why you have to develop the backprop algorithm to train all weights leading
to each of the two output nodes in DNN given in the figure below. Start the training process using
plausible randomly generated weights. After the design of the training algorithm, apply it to model and
forecast a time series, generated using the Mackey-Glass equation (available in the lecture handouts).
Use more lagged inputs and hidden units if necessary to achieve better predictions.
sum
Design a working prototype of the incremental backpropagation for DNN density networks in Matlab.
The prototype development should include data structures for the input-to-hidden and hidden-to-output
connections, and loops for the forward and backward pass.
