I want you to act as an English translator, spelling corrector and improver. You are responsible to revise parts of my research paper that will be submitted to a ML conference. I want you to replace my simplified A0-level words and sentences with more beautiful and elegant, upper level English words and sentences. Keep the meaning same, but make them more literary. I want you to only reply the correction, the improvements and nothing else, do not write explanations.  First repeat the request without change, then give your answer.
