Problem with combining all example set from IO Object Collection

Re: Problem with combining all example set from IO Object Collection

I included a Breakpoint in my solution right after the Collect Operator. It is depicted with a red square symbol.

A Breakpoint pauses the Process and shows the intermediate result.

 

You have three options:

  1. Before starting the Process:
    1. Remove the Breakpoint by clicking on the Operator where the Breakpoint is assigned and press the Shortkey F7
    2. Remove the Breakpoint by rightclicking on the Operator where the Breakpoint is assigned and uncheck the selection "Breakpoint After"
  2. After starting the Process: Resume the Process by clicking again on Run Process (Shortkey F11)

Best regards,

Edin

ah thank you so much, i didn't realize there is breakpoint (im still new with Rapidminer). i'll try with my model

Re: Problem with combining all example set from IO Object Collection

it only appears first example set when joined. Here is my model that i've combined with your xml code. Is there any mistake in my configuration?

Re: Problem with combining all example set from IO Object Collection

The Process itself is correct.

 

The reason for your problem is that each role (as well as attribute name) can only occur once in each exampleset. Therefore the prediction is always overwritten.

Thus you need to change the role for each attribute. In case all attributes have different names you can use a similar solution as depicted in the screenshot below.

Re: Problem with combining all example set from IO Object Collection

one thing that make me curious, in my model that i build, all example set run same neural network model. The thing is every example set have their unique neural network model, right? can i run neural network model with different neuron size, training cycle, learning rate, momentum to each example set? how to do?

You may have a look into the Operator Optimize Parameters (Grid).

Within the Operator Help there is a Tutorial process linked which should point you in the right direction.

yeah i've tried it and i found the best ANN model for each example set but how to apllied it for each example set? if i put it on neural network operator, it only for one Neural Network Model but it means that this one model is applied to all example set right?

Re: Problem with combining all example set from IO Object Collection

i tried the posted solution.

 

I found that i like it with a union operator instead of teh join.  witht he join it would either repeat the column header modified by source it came from or only have one instance of attribute value.

Re: Problem with combining all example set from IO Object Collection

@binsetyawan Since you are doing everything within Loop Attributes, each Attribute has its own model. Does that answer your question?

 

@mskinner I suppose that depends on your use case. Did you just replace the Join with the Union Operator? Since Union simply appends your ExampleSets, the number of examples in the final ExampleSet can drastically increase.
