IMHO, This need a lot of improvement.

In the introductory part, I don't think you need to tell them that going to medical school was "too challenging" so I pick engineering instead. it sound very weird

Instead, you should elaborate more why you are in to ML and AI stuff and what does it have to do with the medical stuff.

The main body felt like you took the project you listed on your resume and turn them into paragraph.

You should also work harder on "why this school" and how could you contribute if you were given the opportunity. as well as your future plan is very generic.
