%description
'Smart Adaptive Recommendations' (SAR) is the name of a fast, scalable,
adaptive algorithm for personalized recommendations based on user
transactions and item descriptions. It produces easily
explainable/interpretable recommendations and handles "cold item" and
"semi-cold user" scenarios. This package provides two implementations of
'SAR': a standalone implementation, and an interface to a web service in
Microsoft's 'Azure' cloud:
<https://github.com/Microsoft/Product-Recommendations/blob/master/doc/sar.md>.
The former allows fast and easy experimentation, and the latter provides
robust scalability and extra features for production use.
