ANECDOTE

Levine's Shift to Machine Learning

  • Sergey Levine switched from computer graphics to machine learning after realizing simulating minds was the key challenge in virtual humans.
  • His first deep learning paper was in 2012 focused on deep reinforcement learning for 3D human motion.
ANECDOTE

End-to-End Deep RL Success Story

  • Levine and his student John Schulman applied end-to-end deep reinforcement learning directly from pixels to motor efforts on a PR2 robot.
  • Their experiments demonstrated end-to-end learning outperformed modular geometric pipelines in robotic manipulation.
ADVICE

Test Extreme Design Extremes

  • In science, test how extreme a design can work to truly understand its value.
  • Isolate new methods instead of patching with existing ideas to gauge their true utility.
