Hi all;

I'm newbie at Rapidminer. I'm using anomaly detection extension. But I cannot use generate ROC operator. I don't know what is wrong with me? I couldn't find any document or video. Is there anyone who can help me about this operator?

Thanks.

    Hi@beyza_kizilkaya,

    Here an example of process (to adapt to your own project) using theGenerate ROCoperator of the Anomaly Detection extension.







    <操作符活性ated="true" class="process" compatibility="8.1.001" expanded="true" name="Process">

    <操作符活性ated="true" class="retrieve" compatibility="8.1.001" expanded="true" height="68" name="Retrieve Titanic Training" width="90" x="45" y="85">

    I hope it helps,

    Hi@lionelderkrikor

    Thanks for your response but I think I couldn't tell my problem. Actually my steps are like this:

    1. I'm importing data as csv or excel

    2. With the help of anomaly detection extension I'm running any algoritm.

    3. And then I'm getting results.

    After these steps I want to create ROC curve with using generate Roc operator which is in anomaly extension too. For this I'm dragging and dropping data file to design page then I'm choosin this operator. I'm doing everything like in help description. But I cannot see anything. Hope it's clear.

    Thanks again.

    Hi@beyza_kizilkaya

    Could you please share the process XML here? So that that we can see where you are going wrong.

    Hi@Pavithra_Rao

    You can find attached .xml file.

    Thanks for your help.

    Hi@beyza_kizilkaya,

    In your process, you don't feed the input portper(performance) of theGenerate ROCoperator , that's why RapidMiner raise an error.

    A ROC is associated to a classification model : So you have to train a model with your dataset and calculate the performance of this model first. To do that, take a look at the template of process I provided in my previous post. Then you can adapt it to your data.

    If you begin with RapidMiner, I encourage you to see the video series about the basics of RapidMiner (how to train a model, how to validate a model etc.) by following this link :

    I hope it helps,

    Regards,

    Lionel
