Let's build a real stream. Scenario: A telecom company wants to predict which customers are likely to cancel their subscription (churn).
Don't know which algorithm to try? Drag the node (Modeling tab). Connect your Partition node. Select 5 algorithms (C5.0, Logistic, SVM, Random Trees, Neural Net). Click Run. Modeler will: tutorial spss modeler
A collection of connected nodes that represent the end-to-end data mining process. Let's build a real stream
The central area where you drag and drop nodes to build your stream. 2. The Standard Workflow: CRISP-DM 98% No Churn
Class imbalance (e.g., 98% No Churn, 2% Yes Churn) kills models. Use the node (Record Ops → Balance). It can oversample the minority class or undersample the majority—click 'Exact Stratification'.
