Damned Memory Example Table Change

leno

Hi to all i have done a process that read a model and apply it to the input data that i give from source code.
My code after init():

      // setup your attribute list
        table = new MemoryExampleTable(master.ListaAttrib);
  //My ListaAttrib has 10 attribute

                input = utile.scalavettor(posx, posy, puntioriginali);
                table.addDataRow(new DoubleArrayDataRow(input));
                  
                exSet = table.createExampleSet();
                ioInput = new IOContainer(new IOObject[]{exSet});

                ioResult = master.process.run(ioInput);
                if (ioResult.getElementAt(0) instanceof ExampleSet) {
                    resultSet = (ExampleSet) ioResult.getElementAt(0);
                    e = resultSet.getExample(0);
                    predettoX = e.getPredictedLabel();
                }

The problem is that code is in a loop and at every iteration the MemoryExampleTable has more Attribute, because the apply model add label and confidence.
With a wrong number of attribute my model don't work.
I try removeattribute but seem that nothing change.

I need it for my Master Thesis everyone can help me?

Hi,

if these attributes are used nowhere else, you can try this line:

exampleSet.getExampleTable().removeAttribute(existingAttribute);

However, if this attribute might occur in other exampleSets or other attribute instances might use the same
ExampleTable's column, you should use this:

exampleSet.getAttributes().remove(existingAttribute);

Marco
