Source: I am a manager who has given offers to top-tier ML experts.
300k+ for a new hire ML/CV/NLP PhD with some relevant experience.
150k+ for a new hire ML/CV/NLP MS with little to no experience
We were working with a very expert ML contractor that is doing 800k on his own from pop-up projects.
The obvious reality is that top people rarely talk about their comp packages, as there is no reason to rock the boat.
Agreed though on total comp for top ML experts who have been around for a while - or the highest end.
The AI scientists, those with work in computer vision, natural language, and audio, developing novel networks and training methods, make at least $500K/year. I've been a data scientist and the pay (and work content) was a joke. I switched to AI and damn, work makes you think and you get paid like a mid-range NBA star.
Theoretically, one would feel, that by just reading blogs, watching videos along side taking MOOC courses, and spawning GPUs on the cloud, should do it.
