What is xLearn?

xLearn is a high performance, easy-to-use, and scalable machine learning package, which can be used to solve large-scale machine learning problems. xLearn is especially useful for solving machine learning problems on large-scale sparse data, which is very common in Internet services such as online advertisement and recommender systems in recent years. If you are the user of liblinear, libfm, or libffm, now xLearn is your another better choice.

Performance

xLearn is developed with high-performance C++ code with careful design and optimizations. Our system is designed to maximize CPU and memory utilization, provide cache-aware computation, and support lock-free learning. By combining these insights, xLearn is 5x-13x faster compared to similar systems.

Ease-of-use

xLearn does not rely on any troublesome third-party library, and hence users can just clone the code and compile it by using cmake. Also, xLearn supports very simple Python and R API for data scientists, and it also offers many useful features that have been widely used in machine learning and data mining competitions, such as cross-validation, early-stop, etc.

Scalability

xLearn can be used for solving large-scale machine learning problems. First, xLearn supports out-of-core training, which can handle very large data (TB) by just leveraging the disk of a PC. In addition, xLearn supports distributed training, which scales beyond billions of example across many machines by using the parameter server framework.
