Recognition rate (%) for a prediction Model
Contributor IHello everybody
That is my Model
First thing I have to say is, I am a beginner with rapidminer. However, I am trying to build a
Predictive Model with a time serie.
- First I prepared the data.
- All attributes are real
- I used the windowing operator
- Now I want to train that model and measure the recognition rate in percentage
- this does not work with any performance operator
- I have no Idea how to solve that problem

May you can give me an input for a solution?

Hi @Mario1,
Can you share your dataset please ?
Regards,
Lionel
Hi Lionel
Thanks for your answer. :-)
Of course in can......
I want to try to predict the attribute "Rechnen". This attribute has only two states. Yes/No; 0,1.
I don't know which one is better......
Regards,
Mario
Hi @Mario1,
I just discovered your dataset.
Windowing operator is adapted for "time series" problems.
In your case, it seems that your problem is not a "time series" problem but a classification problem.
In deed, I suppose you want to predict the value of "Rechnen" according to the value of the other real attributes ?
You can find here a (classic) template of process for a classification task :
I choose arbitrarily a Decision Tree as model, but you can try the different classification models proposed by RapidMiner
to determine which one is the best.
About that, if you are beginner in RapidMiner, I encourage to see the videos about the basics of RapidMiner (how to train a model,
how to validate a model, how to apply a model, how to optimize a model etc.) by following this link.
I hope it helps,
Regards,
Lionel
