I want to get into professional ML/AI. I'm working as full time software engineer for 3 years now and I'm looking to pick up some high-end skills in AI/ML after going through the basics in Coursera, Edx. I'm looking for a review of the past term in the program since it is VERY costly for someone from eastern Europe so I want to make sure I'm not making a stupid move by paying for the AI nanodegree in which I have been offered a place.
