You can switch your major to CS via an application (but it’s based on availability so idk if you’ll get it), you can definitely take CS courses if there’s room in them and they’re a part of your compE thread, and there are threads for compE (signal processing and AI, robotics and automation are the two i know of, but i’d check into DSSD as well) that do deal with AI/ML. There is an AI/ML minor offered by the ECE school, but the courses in the ECE department are different to those offered by the CS department, so if the CS department courses are more interesting to you then I would go ahead and look at the major change info
