xLearn is developed by high-performance C++ code with careful design and optimizations, and it is 5x-13x faster compared to the similar systems.
xLearn does not rely on any troublesome third-party library, and users can just build it easily. Also, xLearn supports very simple Python and R API for data scientists.
xLearn supports out-of-core training, which can handle very large data (TB) by just leveraging the disk of a PC. Also, xLearn supports efficient distributed training.
