I am building a file with sample data that has a bunch of variables:
time_since_last_transaction etc. that i am mapping against
I will train my model using Keras to map the emboldened variables to the italicised
days_to_churn. However there are many instances where a user is an active subscriber and this value is blank.
How would I go about incorporating this to ensure that I am not excluding active people from my churn calculations?
