Activate catalog¶

See SDK reference for catalogs

In [ ]:

catalog = fb.Catalog.activate("Grocery Dataset Tutorial")

catalog = fb.Catalog.activate("Grocery Dataset Tutorial")

Get view from table¶

See SDK reference for views

In [ ]:

# Get view from GROCERYINVOICE event table.
groceryinvoice_view = catalog.get_view("GROCERYINVOICE")

# Get view from GROCERYINVOICE event table. groceryinvoice_view = catalog.get_view("GROCERYINVOICE")

Do window aggregation from GROCERYINVOICE¶

See SDK reference for features

See SDK reference to groupby a view

See SDK reference to do aggregation over time

See SDK reference for feature group

See list of aggregation operations

In [ ]:

# Group GROCERYINVOICE view by customer entity (GroceryCustomerGuid).
groceryinvoice_view_by_customer =\
groceryinvoice_view.groupby(['GroceryCustomerGuid'])

# Group GROCERYINVOICE view by customer entity (GroceryCustomerGuid). groceryinvoice_view_by_customer =\ groceryinvoice_view.groupby(['GroceryCustomerGuid'])

In [ ]:

# Get Latest invoice Timestamp for the customer
customer_latest_invoice_timestamp =\
groceryinvoice_view_by_customer.aggregate_over(
    "Timestamp", method="latest",
    feature_names=["CUSTOMER_Latest_invoice_Timestamp"],
    windows=[None]
)["CUSTOMER_Latest_invoice_Timestamp"]

# Get Latest invoice Timestamp for the customer customer_latest_invoice_timestamp =\ groceryinvoice_view_by_customer.aggregate_over( "Timestamp", method="latest", feature_names=["CUSTOMER_Latest_invoice_Timestamp"], windows=[None] )["CUSTOMER_Latest_invoice_Timestamp"]

Derive Time Since feature from latest timestamp¶

See SDK reference to derive time since features

In [ ]:

# Compare CUSTOMER_Latest_invoice_Timestamp with point-in-time in days
customer_time_since_latest_invoice_timestamp = (
    fb.RequestColumn.point_in_time() - customer_latest_invoice_timestamp
).dt.day
# Give a name to new feature
customer_time_since_latest_invoice_timestamp.name = \
"CUSTOMER_Time_Since_Latest_invoice_Timestamp"

# Compare CUSTOMER_Latest_invoice_Timestamp with point-in-time in days customer_time_since_latest_invoice_timestamp = ( fb.RequestColumn.point_in_time() - customer_latest_invoice_timestamp ).dt.day # Give a name to new feature customer_time_since_latest_invoice_timestamp.name = \ "CUSTOMER_Time_Since_Latest_invoice_Timestamp"
