Take away from "Lessons from My First Two Years of AI Research"

Just read an interesting post at  Lessons from My First Two Years of AI Research . Some takeaways: - First advice: write - Invest in visualization. - There are 3 perspectives on AI motivations: math, engineering and bio. - 3 ways to get research ideas: Talk to a researcher in a different field. Code a simple baseline to get a feel for a problem. Extend the experiments section of a paper you like. My personal lesson: I do not need to think about a problem all the time but I need to avoid all distractions.
