I am currently a 2nd year PhD student at a university in Canada. My PhD program is about environment chemistry. For a long time I wanted to learn computer science, especially machine learning, and I have 1 year work experience in an IT company.
I do not have a diploma in CS, though I have learned some course about programming and have experience in some programming languages.
Now I realize that I do not like my current research about chemistry, and my research has little progress recently. I also keep thinking about changing my PhD program or transfer to another program. I am particularly interested in machine learning, and relevant researches.
What ways can lead me to that track ? Thank you.
