Polynomial Regression
Exercise 6.1
Apply the third-order polynomial regression modeler to the sqFtBath dataset.
Does it improve upon the second-order polynomial model? Explain your answer.
ANN Modeling
The third regression algorithm available in VisMiner is the artificial neural
network (ANN). The advantage of the ANN is that it is capable of fitting a more
complex surface.
Drag the ANN regression modeler over the sqFtBath dataset and drop.
Choose “Build interactively”, then select price as the prediction column.
The interactive build option allows user control over the training process.
The effectiveness of ANN training depends on the learning rate and momen-
tum, yet there is no single best learning rate or momentum for all datasets. It
will vary from dataset to dataset. The interactive build option allows you to
monitor the training progress while adjusting the learning rate and momentum
as it trains.
