Hello,

I'm trying to run a sentiment analysis using linear svm. I'm reading my data from a sql server. However on the apply model (2) in the xml below I receive the below error each time. Would you have an idea why this is occurring ?

the input example set does not match the training example set. missing attribute aaaa

    Hi there,

    At first glance I'd suggest that you do all your pre-processing before the validation, as you are set up only the training examples get filtered and re-typed, the testing examples therefore have different attributes and RM gets confused..

    Hope that works!

    Best wishes,

    Thanks Haddock.

    Most of the pre-processing is done before it arrives in RM via an ETL process on SQL.

    Are you suggesting removing the below outside of the x-validation operator ?

    Yep Indeedy!

    The point is that the training and testing example sets need to have the same attributes; something like the following is better..

    Thanks for the XML Haddock. Unfortunately I get the same error.

    The input ExampleSet does not match the training ExampleSet. Missing attribute:aaa

    The operator expects the input to have a set of Attributes which is equal or a superset of the ExampleSet used for training of the input model.
    Please make sure that the attributes of the two example sets satisfy this condition.

    Cause: Apply Model

    Hi there,

    You are training on one set of attributes, and testing on another; put a break before each model applier to check that they are all using the same set of attributes.

    Ciao,
