SOP for PhD computer science with emphasis on machine learning

Any feedback would be highly appreciated. Thanks in advance ;)

Introduction
It's undeniably obvious that machine learning is the leading field that has achieved the best advancements of Artificial intelligence in the recent years. These advancements have came to light after enormous datasets have started becoming available and the computing power reached a level that allowed it to handle such huge amounts of data. I have since been interested in artificial intelligence and especially machine learning as a subfield with a dream that its name could be literally achieved with intelligence and learning that are on par with the human level.

Education
During my middle years of undergraduate school of medicine, I started exploring the field of computer science as it was just a hobby back at these times and I've enjoyed the challenges that it puts me in. I started taking online courses by myself to learn the basics of programming, algorithms and mathematics. At the end of my college I started doing some freelance projects for a couple of startups including web and iOS applications (some are still available on the appstore). During these times I was used to participate in online programming competitions too including TopCoder, CodeJam, etc.

After finishing my bachelor degree (MBChB) I looked for how to shift my career officially into computer science. I liked the idea of how to solve problems that haven't been solved before. I joined the Information Technology Institute (ITI) to get a 9 months diploma in programming Java Web and Enterprise applications. I finished the first of my class and I didn't just learn deeply about software engineering concepts to be a better engineer but during this period I also got introduced to machine learning in ITI and at the same time I was able to finish the Andrew Ng course on coursera about machine learning. After that I got accepted to a master's program in Istanbul Sehir University.

Research Experience
In my master's degree I have so far finished all my courses with an A grade. Also since I came here I have started working as a research assistant under the supervision of Professor Ali Cakmak in the \href{http://biodb.sehir.edu.tr/}{Bioinformatics and Databases Lab} doing research in the metabolomics data analysis project.

Main Research Project
Our main research target is to develop a personalized medicine technique to diagnose diseases earlier using a model that wouldn't just do this but also provide better understanding of how these diseases develop and help care takers to take more personalized decisions for treatment. Our currently used techniques to develop this model include some machine learning models that help in extracting significant features considering metabolites and reactions that contribute the most to a special case/disease.

I have done some short term research projects as a part of the classes that I have took so far in my master's degree:

Project #1
Predicting negative keywords for online search advertisements. I reviewed more than 10 research papers in that topic and improved on an already existing technique to be more efficient and wrote a paper on it (although not published).

Project #2
Taxonomy classification of organisms based on DNA barcode using LSTM neural networks. After reviewing the existing techniques already present (Random Forests, logistic regression and Convolutional neural networks) I used Torch to implement an LSTM neural network to do this classification but the existing techniques achieved better results than the LSTM which might be due to the lacking of enough data to train the network.

Project #3
Genetic factors that correlates with glioma aggression within G-CIMP cancer subtypes. We used statistical methods, PCA and logistic regression for predicting these genetic factors.

Teaching Experience
These so far weren't the only drivers to pursue a PhD position but also me valuing the career of being a professor who teaches future generations and explores uncharted territories of science. I've always loved teaching and I think I was good at it. I used to teach animation in the first years of college, taught some computer science concepts to some students in ITI and in Istanbul Sehir University I was teaching Java (our school teaches in Python) and some machine learning concepts to some undergrad students. All of these were under the name of students' activities as I was a research assistant and didn't have teaching duties. Students mostly gave me surprising feedback that I was even teaching better than some professors and that I would be some day be a good professor/teacher.

Concluding Remarks
I have always tried to improve my knowledge about Artificial intelligence as I've always dreamed since childhood to be one of the pioneers of this magical field that has been involved in most of my favourite sci-fi books and comics. On the practical side I've found that my passion and my reason for what's going to be the next big thing in AI advancement directed me to focus on the branch of machine learning. Hence, I hope that these reasons along with my experience that I have tried my best to further develop it in the past few years could land me a PhD student position in <UNIVERSITY> to pursue computer science with an emphasis on machine learning and its applications in different fields.

Mohamed, when you are writing a PhD statement of purpose, your educational information should focus more on what you learned in graduate school rather than giving a run down of your college education, interests, and eventual career shift. It is understood that when you are applying to PhD school, that you have at least 5 years work experience under your belt. All of which should be relevant to your current or increasing interest in Machine Learning.

As for your research experience, you do not need to present all 3 in the statement. You need to only present your most impressive research. It would help if the research had been published so that you can refer to yourself as an authoritative and published participant in this field. Published work will also add to the validity of your application because that information can be verified and reviewed by the reviewer as part of additional consideration for your application.

In your concluding remarks, do not refer to a dream from your childhood in reference to your plans for your career in this field. Instead, simply say that you have always dreamed of excelling in this field. Reviewers do not believe and are never impressed by claims of childhood dreams. Mostly because as a child, your influences, in this case comic books and sci-fi books cannot be considered real influences on the ambitions and dreams of a person later on in life.
