The Filter block enables you to reduce the total number of observations in a large dataset. The following demonstrates how to use the Filter block to reduce the size of an input dataset loan_data.csv (containing observations each of which describes a completed loan and the person who took the loan out) using the numerical…
The Decision Tree block enables you to apply a Decision Tree predictive model to an input dataset. The following demonstrates how to use the Decision Tree block to predict a dependent Score variable from an input dataset basketball_shots.csv (containing observations that detail a basketball shot in a professional game and…
The Decision Forest block enables you to apply a decision forest predictive model to an input dataset. The following demonstrates how to use the Decision Forest block to model the Default variable from the loan_data.csv dataset (containing observations each of which describes a completed loan and the person who took the…
The Aggregate block enables you to apply a function to create a single value from a set of variable values grouped together using other variables in the input dataset. The block is used to generate basic statistics for the input loan_data.csv dataset (containing observations each of which describes a completed loan and the…
The WoE Transform block enables you to measure the influence of an independent variable on a specified dependent variable, for example to measure risk, and apply variable transformation, for example to transform variables into a finite number of bins and output the results. The following demonstrates how to use the WoE…
The Text Transform block enables you to define operations used to manipulate the contents of variables from an input dataset. The following demonstrates how to use the Text Transform block to remove punctuation from a variable in the input dataset lib_books.csv (which contains observations that describe a range of books…
The Text File Import block enables you to import data from a text file, for example a CSV file, into a Workflow. The following shows how to import a CSV file ( basketball_shots.csv ) saved in the Workbench workspace: * Expand the Import group in the Workflow palette, then click and drag the Text File Import block onto the…
The Sort block enables you to order a dataset based on one or more variables. The following demonstrates how to use the Sort block to sort an input dataset lib_books.csv (which contains observations that describe a range of books available from a lending library) using the values in the Author variable: * Import the…
The Select block enables you to keep or discard variables in a dataset. The following demonstrates how to use the Select block to retain the Author variable from the lib_books.csv dataset (which contains observations that describe a range of books available from a lending library): * Import the lib_books.csv dataset onto a…
The Scorecard Model block enables you to create a scorecard model consisting of a set of attributes each with an assigned weighted score (either positive or negative). The following demonstrates how to use the Scorecard Model block to create a scorecard with a logistic regression model and a WoE Transform block. Two input…
