AI Experts Advice on Learning AI as a Beginner
“Don’t chase after the hottest trends or the biggest splashes, as these areas will have the most competition and also will likely be superseded quickly anyway. Think about what kinds of problems you’re most interested in solving, and what problems are likely to make the most impact if solved. The first involves being aware of what kinds of work you like doing (programming, theorizing, playing with real-world data, etc), and the second involves looking around and being informed about how the rest of the world lives. ”
– Jane Wang, Senior Research Scientist, DeepMind
“1. Learn the foundations. “Hands-on” alone, without an understanding of the underlying math, will not let you become the best in this profession. Today, and especially in the next 5-7 years, the tools will become so mature, that only your imagination will count. In AI, you cannot imagine anything meaningful if you don’t know how the machine “thinks.” Take a sculptor, an architect, or a painter. The best of them know everything about the tools and materials they work with. The same is true for AI.2. Go where the data is. AI is nothing without data, just as your talents.”
– Andriy Burkov, Director of Data Science, Gartner
