PRODUCT Variability of customer Age band based on item TotalCost 28d

SDK code to create PRODUCT_Variability_of_customer_Age_band_based_on_item_TotalCost_28d¶

Feature description:

The feature evaluates the distribution of a product's item's TotalCost across various customer_Age_band categories over a 28d period using entropy. Higher entropy signifies a more uniform distribution of item's TotalCost across categories, while lower entropy suggests a concentration within specific customer_Age_band categories.

Get view from table¶

See SDK reference for views

In [ ]:

# Get view from INVOICEITEMS item table.

Join views¶

See SDK reference for views

In [ ]:

# Join GROCERYCUSTOMER view to INVOICEITEMS view.
invoiceitems_view = invoiceitems_view.join(grocerycustomer_view, rsuffix="")

# Join GROCERYCUSTOMER view to INVOICEITEMS view. invoiceitems_view = invoiceitems_view.join(grocerycustomer_view, rsuffix="")

Derive Timedelta from datetime column¶

See SDK reference for view columns

In [ ]:

# Derive Age from the event timestamp and the date of birth.
invoiceitems_view["customer_Age"] = (
    (
        invoiceitems_view["Timestamp"]
