PHP-ML is an open source project. If you'd like to contribute, please read the following text. Before I can merge your Pull-Request here are some guidelines that you need to follow. These guidelines exist not to annoy you, but to keep the code base clean, unified and future proof.
You should only open pull requests against the master branch.
Please try to add a test for your pull-request. You can run the unit-tests by calling:
bin/phpunit
GitHub automatically run your pull request through Travis CI against PHP 7. If you break the tests, I cannot merge your code, so please make sure that your code is working before opening up a Pull-Request.
Please allow me time to review your pull requests. I will give my best to review everything as fast as possible, but cannot always live up to my own expectations.
When contributing code to PHP-ML, you must follow its coding standards. It's as easy as executing ./bin/php-cs-fixer fix in root directory.

Thank you very much again for your contribution!
