I upgraded Rapid Miner Studio 7.3 version to 7.4, now I cannot retrieve the topology of the Neural Net in the results section.
Can you pls help how can I retrieve the topology of the network in 7.4?
Also is it possible to see predicted reuslts after applying the model?
In the results section I can only see Performance results as well as the weights.
I assume you are using the Cross Validation operator.
To see the model (the Neural Net), you need to connect the "mod" output of the Cross Validation to the process output.
To see the predictions, the "tes" output must be connected.
Thank you for yr kind reply.
I used Split validation, anyhow tried the steps you mentioned, but now faced another problem in my data set (from repository).
The system detected a problem and the error message read as "this may not be portable when sharing process"
I really don't understand, I made every steps successfully in Rapid Miner 7.3 without any error messages.
Now in Rapid Miner 7.4 many error messages that I cannot clear. See most of the features have been changed.
I really don't know how to fix the error message
Have a nice day.
That error relates to how you set up your process and data repository. It's just giving a warning to say that if you were to share this process and data, it's not in a relative path type of format and may break on some other users PC. Nothing to worry about unless you are collaborating with others.

Many thanks for yr kind reply.
I fixed the problem however now facing with another difficutly.
I have 62 months data set and tried to prdict 63th month.
I run all the processes from yr videos successfully but cannot see any 63th month data.
I know I'm missing a point, but could not find it. I need to show it on my PhD thesis.
I'd be glad if you'd assist.
Thanks you for yr kind concern.
Have a nice day.

Ok, is this a time series problem? If yes, are you using the Sliding Window Validation operator?
Take a look at the sample process I posted here: http://community.rapidminer.com/t5/RapidMiner-Stud
That will do point forecasting on a time series. I used an SVM but you can swap it out for a ANN.
