## Semagle F# Framework

Applied machine learning developers have a lot of open-source machine learning frameworks, e.g., ScikitLearn, Spark MLlib, ML.Net, etc. Frameworks provide a user-friendly high-level interface to algorithms, but implementations resort to low-level languages and optimizations. Such low-level C/C++, C#, or Java code is far from the original mathematical notation that is preferable for machine learning algorithms research and development. Semagle Framework makes the most of low-level C#-like constructs for performance optimization and high-level semi-mathematical F# notation for joining the algorithm blocks. Modularization of algorithms with fine-grained blocks makes research and development of new implementations for the same family of problems straightforward.
