Building the flow

  1. Add a Data Asset node that points to telco.csv.

  2. Attach a Type node to the Data Asset node. Set the measure for the churn field to Flag, and set the role to Target. Make sure the role for all other fields is set to Input.

  3. Attach a Logistic node to the Type node.

  5. Attach an Auto Data Prep node to the Type node. Under OBJECTIVES, leave the default settings in place to analyze and prepare your data by balancing both speed and accuracy.
  6. Run the flow to analyze and process your data. Other Auto Data Prep node properties allow you to specify that you want to concentrate more on accuracy, more on the speed of processing, or to fine tune many of the data preparation processing steps.
    Note: If you want to adjust the node properties and run the flow again in the future, since the model already exists, you must first click Clear Analysis, under OBJECTIVES before running the flow again.
