Once upon a time PhD supervisors were recommended a phdcomics website.
Literally, ‘phd’ here stands for ‘Piled Higher and Deeper’ – the paper swamp with so many of us still trapped in.
This cartoon is thought provoking: what is our ‘unanswerable’ question is machine learning / computer vision? Here’s my try:

  • “Hey dad, can your program tell the twins apart?”
  • “Can your algorithm be parameters free?”

Any more?
