class SAR extends Estimator[SARModel] with SARParams with DefaultParamsWritable with SynapseMLLogging

Smart Adaptive Recommendations (SAR) Algorithm

https://aka.ms/reco-sar

SAR is a fast scalable adaptive algorithm for personalized recommendations based on user transactions history and items description. It produces easily explainable / interpretable recommendations

SAR has been show to provide higher ranking measurements when compared to ALS. https://github.com/Microsoft/Recommenders
