The work to implement
SVD++ is more than I have expected, and this task takes more time than scheduled. For the past two weeks, I first debug the errors in
BiasSVD (thanks to Mikhail's careful review), and then finished the implementation of
SVDPlusPlus class. After making sure that
SVDPlusPlus is working reasonably, I implemented wrapper classes of
SVDPlusPlus which are used by
CFType<> as decompostion policy. Then, I refactored
CFModel so that the pointer to the actual model class is saved as
SVD++ are not supported in cf executable yet. I will implement the supports after this PR is merged (so that we are sure
SVD++ are working properly). I also spent quite some time in debugging the Travis Test failure with regard to armadillo.
For the next week, I will carry on implementing test cases and complementing code comments. I will also start to work on CF benchmarking if time permits.
