New features in IBM SPSS Modeler 18.3.0

IBM® SPSS® Modeler adds the following features in this release.

  • An inconvenience with modeling is models getting outdated due to changes to your data over time. This is commonly referred to as model drift or concept drift. To help overcome model drift effectively, SPSS Modeler now provides continuous automated machine learning. A result of IBM research, and inspired by natural selection in biology, continuous machine learning is available for the Auto Classifier node and the Auto Numeric node. For more information, see Continuous machine learning.
  • You can now upload streams to an IBM Cloud Pak for Data server directly from IBM SPSS Modeler client. For more information, see Saving streams to IBM Cloud Pak for Data.
  • If you want to enable logging for IBM SPSS Modeler client, open the file log4j2.xml in a text editor and change level="info" to level="debug" in this line:
    <Logger name="com.spss" additivity="false" level="info">
  • A new setting called Perform non negative least squares has been added to the GLE node on the Build Options tab under Parameter Estimation. Non-negative least squares (NNLS) is a type of constrained least squares problem where the coefficients are not allowed to become negative. Not all data sets are suitable for NNLS, which requires a positive or no correlation between predictors and target.
  • A new setting called Lines to scan for column and type has been added to the Excel Source node. The default value for this new setting is 200. If you need to increase this value to scan more rows of your Excel data to determine the column type and storage type, note that performance may be impacted.
  • A new connection method (TM1 Server connection) is available for the IBM Cognos TM1 Source node and the IBM Cognos TM1 Export node to support Planning Analytics on Cloud. The Admin Server has been removed from Planning Analytics on Cloud, so if you have old streams containing TM1 nodes that connect to Planning Analytics on Cloud through TM1 Admin Server, you can now modify them to point to TM1 Server instead.
  • Db2 11.5 is now supported.
  • Db2 Warehouse is now supported.
  • Db2 Big SQL 7.1.0 on Cloudera Data Platform 7.1.5 is now supported.
  • Apache Hive 3.1.3 on Cloudera Data Platform 7.1.5 is now supported.
  • Cloudera Impala 3.4.0 on Cloudera Data Platform 7.1.5 is now supported.
  • Informix 14.10 is now supported.
  • RedHat 8.3 is now supported.
  • A new version of R is used (4.0.4).
