Re: Universal Recommender : seasonality of product

You can’t keep data forever or your storage needs will grow without bounds. At 
some point you will need to trim it to maintain a moving window in time. Some 
E-Com applications maintain a year of data if their items have relatively long 
lifetimes in the catalog.

You may need to use the db-cleaner template to trim your data to whatever 
amount you want to keep. This time-window defines the expiration of the 
blacklist.

Hi Pat,

Thank you for the reply.
So what do we mean when we say "ages out of the data"?

maintain 1 year of data, then a year after the user bought the particular table 
they might get a recommendation for it. In other words the blacklist expires 
with the last event in the input data.

Hi, 

Is there a way to add seasonality of products:
eg: If I buy a table now, I would not want to recommend tables again for the 
next year. 

So how could I include this seasonality into making recommendations?

Thanks.

This is done with blacklisting. The default config blacklists all items in the 
training data that the users has taken the primary event on. So if your primary 
event is “buy” then once a user has bought a particular table they will not be 
recommended that table again until the “buy” event ages out of the data. If you 
maintain 1 year of data, then a year after the user bought the particular table 
they might get a recommendation for it. In other words the blacklist expires 
with the last event in the input data.

Universal Recommender : seasonality of product

[Saarthak Chandra]

Hi,

Is there a way to add seasonality of products:
eg: If I buy a table now, I would not want to recommend tables again for
the next year.

So how could I include this seasonality into making recommendations?

Thanks.
