[KNIME Nodes] KN-121 Advanced Data Generation

Generates Customer Profile sample data using advanced data generation techniques. All of the nodes used in this example come from KNIME. These nodes can be used as an alternative to the Market Simulation data generation capabilities.

KNIME Nodes (KN-121) - Advanced Data GenerationGenerates Customer Profile sample data using advanced data generationtechniques. All of the nodes used in this example come from KNIME. These nodescan be used as an alternative to the Market Simulation data generationcapabilities. This example is originally based upon the KNIME workflow called "Scalable DataGeneration" but has been cleaned up with step-by-step explanations. The requiredExtensions include: (1) KNIME Data Generation, and (2) KNIME JSON-Processing.See Also: https://hub.knime.com/knime/workflows/Examples/50_Applications/53_Performance_and_Scalability/01_workflows/00_Scalable_Data_Generation Step 4: Generate an appropriateIncome for all Customers basedupon their Age Generation andwhether they are a Student. Step 5: Shred the Income ofsome Customers based uponthe Probability that they are notcurrently working. Step 6: Clean up the finalCustomer Profiles by roundingthe Income, removing extracolumns, and sorting byCustomerID. Step 1: Create 200 RandomCustomers (48% Male / 52%Female) with Customer RowID'srunning from c0 to c199. Step 2: Use 6 Age PyramidProfiles to randomly allocate theage of these Customers frombetween 17 years old and 100years old. Advanced Data Generation Steps:1. Generate list of 200 Male / Female Customers2. Create a Population Age Pyramid using 6 x Pyramid Profiles3. Assign all Customers an Occupation based upon Age Probability4.
