<p>This examples demonstrates how to modify E-Commerce Recommendation template to further
adjust score.</p><p>By default, items have a weight of 1.0. Giving an item a weight
greater than 1.0 will make them appear more often and can be useful for i.e. promoted products.
An item can also be given a weight smaller than 1.0 (but bigger than 0), in which case it
will be recommended less often than originally. Weight values smaller than 0.0 are invalid.</p><p>You

PredictionIO is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored
by the Apache Incubator. Incubation is required of all newly accepted projects until a further
review indicates that the infrastructure, communications, and decision making process have
stabilized in a manner consistent with other successful ASF projects. While incubation status
is not necessarily a refl
 ection of the completeness or stability of the code, it does indicate that the project has
yet to be fully endorsed by the ASF.</span></div></div></div><div
