> We should add an example for using Spark and MLlib to build an item
> recommender.
> Two challenges:
> 1. The data generator does not generate user product ratings. We need a way
> to provide a metric for the "strength" of an interaction between a user and
> product. This could be the normalized purchase frequency for each product.
> Further evaluation is needed.
> 2. How to evaluate the recommendations. We will want to divide the user
> data into 2 groups: validation and training. For the validation group, we
> may want to drop certain products and see if the recommender fills in those
> products or something similar.
