Jul 2008 - Jan 2019
Role in this project:Back-end Developer & ML Engineer
Back-end Developer & ML EngineerContributions:1 release, 2170 commits, 15 PRs in 10 years 7 months
Contributions summary:Jeffrey's commits reveal significant contributions to the core functionality of the Encog Java core, focusing on genetic programming (GP) aspects. The user implemented unit tests for key features like crossover, created and integrated mutation algorithms (subtree mutation), and integrated core machine learning capabilities, for example, adding support for tournament selection. Further, the user designed and implemented a code to enable the software to perform with parallel computing with a combination of multi-threading. Additionally, the user worked with concepts like type checking in the project.
