Is There a Way to Visualize the Decision Tree AML Used?

Sean L 16

I have used a Two-Class Boosted Decision Tree in Azure ML to make some predictions on data that I am analyzing. Once the model has completed training is there a way for me to visualize the structure of the decision tree that was ultimately used by Azure?

Hello,

Thanks for reaching out to us. If you are under Azure Machine Learning Studio(Classic), you can easily do it by Right-click on the output node of the "Train Model" module and select "Visualize".

@YutongTie-5848 is it possible if you are not using Azure Machine Learning Studio (Classic)?

Sure.

For example if you are using scikit-learn and python, you can visualize as below:

Is there any product of Azure ML you are using?

I am using the base Azure ML Designer. I have not written scripts myself using Python.

Hello,

I don't think there is this function in Designer without coding, but I can check around and let you know.

Hello,

I have confirmed we don't have visualize function for Azure Machine Learning Designer now, but we would like to learn why you are asking about this feature and what you want to do with the visualized graph. We are caring customers' experience and will consider this function if that makes sense.

Hi Yutong,

We are doing data analytics and would like to see exactly how the Decision Tree decides on how to categorize two different classes to see if they line up with our predictions. In the AutoML section of Azure ML it is possible to see which features were most important in the classifications, and how they played a role, but we cannot directly see this sort of analysis when using the Designer.

While I would normally just switch to the older Azure ML Studio which has the ability to view the Decision Tree created, this is not feasible since the data we have must be housed in Canada which doesn't seem to be possible with ML Studio.
