Hi 

I have try to use the auto model tool for forecasting. The excel data i imported in have 1000 rows. But when the prediction results that is out for the linear model and deep learning, there is only half of it (~500 rows). Why is this so?

Please advice.

Thanks!

    Hi @Judy

    It's not an issue. It's an evolution of RapidMiner 9.1.
    Now, by default in AutoModel, RapidMiner performs a data split with 60% for training the model and 40% for testing the model.(See the Split Data operator in the generated process).
    The predictions are only performed on the test set. So for a dataset of around 1000 examples, there are around 0.4 * 1000 = 400 predictions.

    I hope it helps,

    Regards,

    Lionel
