I’m in the same cohort, and I’m also a civil engineer.
Since you started your AI journey in March 2016, you are way ahead of me. I only started on it in November, first in taking the Udemy Machine Learning A to Z course ( very good, by the way), and that launched me into AI shortly thereafter. I’ve been devouring as much AI material as I could since then.
It’s been about 10 years since I’ve done any serious coding, so I’m learning as I’m going along in this Udacity AIND.
There are so many areas to apply AI. My interests are currently in cybersecurity, robotics, and environment.
I look forward to reading more about your experiences in the Udacity AIND course.
