Add Model to Structure |

Select Structure |

Select Algorithm |

Then, we need to select the "Microsoft Neural Network" algorithm. Let's take a look at the parameters.

Parameters |

The more observant views might notice that the only difference between these parameters and the Logistic Regression parameters is the addition of Hidden Node Ratio. This makes perfect sense because, as we said earlier, the Logistic Regression algorithm is simply the Neural Network algorithm with no hidden layer, i.e. Hidden Node Ratio = 0. The Hidden Node Ratio is most useful parameter in this algorithm and can be used to drastically change the model. For more information about these parameters, read this. Let's move on.

Create Model |

Finally, we need to create the model. Let's check out the results.

Discrimination Report |

This Discrimination Report says that we should focus on customers from the Pacific, have a Professional occupation, 1 car, or 3 kids. You can keep going with that logic for as long as you need. Just for kicks, let's see what happens if we try a couple different values for Hidden Node Ratio.

This model has a Hidden Node Ratio of 1. This model still has most of the same favorable attributes as the previous one. That's a good thing because it implies that the model is stable, and therefore good. Let's try a Hidden Node Ratio of 10.

This model looks pretty similar to the others as well. We should note that we can't suggest stability of the model by using the Discrimination Report. What we really need to do is see how much the predicted values vary, or don't vary, across the models. Even better, we could compare the predictions from the Neural Network models to the other classification models we've built previously. However, we're not quite there yet. Keep an eye out for our next post where we'll be talking about Accuracy Charts. Thanks for reading. We hope you found this informative.

P.S.

We wanted to discuss the Sequence Clustering Algorithm next. However, we can't add a Sequence Clustering Model to a Structure without a Sequence ID, yet we can't find a way to create a Structure with a Sequence ID. So, if you know anything about building a Sequence Clustering Model using the Excel interface, let us know in the comments.
