What is SPSS Modeler?

SPSS Modeler is a data mining application, where you can build data mining SPSS Modeler flows by using the visual interface. Programming is not required. You can build SPSS Modeler flows to explore your data, model outcomes, try different models, and investigate relationships to find useful information. SPSS Modeler uses the Cross-Industry Standard Process for Data Mining (CRISP-DM) methodology, which is an industry-proven way to guide your data mining efforts.

Using the Flow Editor, you prepare or shape data, train or deploy a model, or transform data and export it back to a database table or a file in Cloud Object Storage. Running an SPSS Modeler flow consumes capacity unit hours. For more information, see Watson Studio environments compute usage.

You can use the advanced analytics in SPSS Modeler to discover patterns in your data and tune models. You can then deploy these models in your business to make predictions on new data with unknown outcomes. The models can systemically analyze data and find business insights and opportunities. If you have access to the watsonx.ai Runtime service, you can promote models to deployment spaces to run them.

Data formats

• Relational: Tables in relational data sources
• Tabular: Tables in data files such as .xls, .csv, .json, or .sas. For Excel files, only the first sheet is read.
• Textual: In the supported relational tables or files

For more information about the file types that are supported, see Supported data sources for SPSS Modeler.

How can I prepare data?

• Use automatic data preparation functions
• Write SQL statements to manipulate data
• Cleanse, shape, sample, sort, and derive data

How can I analyze data?

• Visualize data with many chart options
• Identify the natural language of a text field

How can I build models?

• Build predictive models
• Choose from over 40 modeling algorithms, and many other nodes
• Use automatic modeling functions

Scripting

You can use scripting in SPSS Modeler to automate tasks that are highly repetitive or time consuming to perform manually. Scripts can perform all the same types of actions as users with a mouse or a keyboard, and you can write scripts in R, Python, or Python for Spark.

The following are some of the tasks that you can automate with scripts:

• Impose a specific order for running nodes in a flow
• Set properties for a node
• Set up a process that automatically takes a model training flow, runs it, and produces the corresponding model-testing flow.
