Alternatives to Neighborhood-Based CF - Week 10 & 11
The work to implement BiasSVD
and 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 BiasSVD
and 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 boost::variant<...>
. BiasSVD
and SVD++
are not supported in cf executable yet. I will implement the supports after this PR is merged (so that we are sure BiasSVD
and 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.
