This package provides the following:
An R interface to the Azure Product Recommendations service, a cloud implementation of SAR. It includes the ability to deploy the backend via the AzureRMR package, as well as a client frontend.
A standalone R implementation of SAR, for ease of experimentation and familiarisation. The core algorithm is written in C++ and makes use of multithreading and sparse matrices for speed and efficiency.
Other SAR implementations:
These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
