In [0ff122ec96d2bde6d42ee74aea1bb9dff45838a1]:
Add `BaselineRatingPredictor` to allow baseline evaluation (closes #28)
* Implement `BaselineRatingPredictor`, a `DynamicRatingPredictor` delegating to a baseline predictor.
* Document difference between `BaselineRatingPredictor` and `BaselinePredictor`
* Turn off the default `@Normalized` binding so recommenders don't demand normalizers unnecessarily
Also, makes `ScriptedRecipeBuilder` public so scripts actually work.

Two ways to do this:
- Introduce
BaselineRatingPredictor
as aRatingPredictor
that is backed by aBaselinePredictor
. - Introduce
AbstractBaselinePredictor
, subclassed by all baselines, that also implements theRatingPredictor
andDynamicRatingPredictor
interfaces.
(1) has naming confusion (what's the difference between a BaselinePredictor
and a BaselineRatingPredictor
?). (2) introduces complications with session/built distinctions for baselines with precomputed values (global mean, item means) - basically, any baseline predictor will need to be noticeably more complicated.
