SPSS MODELER (Version 18.2) very slow performace with lagre number of Columns

  • 1.  SPSS MODELER (Version 18.2) very slow performace with lagre number of Columns

    Posted Tue July 21, 2020 10:11 AM

    For predicting time series with machine learning algorithms it is usual that you "lag" your columns many times (For Example 12 -24 times for monthly predictions). For example if you have initially 150 columns, you get after lagging them 24 times 24 * 150 --> 3600 columns.

    Here comes my problem: SPSS Modeler is terribly slow. Even if you change something like a filter node, you add a source, you make any interaction like unlink nodes, deactivate node... and so on, you have to wait up to 1 minute for any change. All of that just because of many Columns.

    What can I do here? Is there any setting i have to adjust? I already did dimension reduction with feature generation, filtering out columns with poor correlations...

    Thank you!

    Greetings Adam
