BI 087 Dileep George: Cloning for Cognitive Maps

When a waiter hands me the bill, how do I know whether to pay it myself or let my date pay? On this episode, I get a progress update from Dileep on his company, Vicarious, since Dileep's last episode. We also talk broadly about his experience running Vicarious to develop AGI and robotics. Then we turn to his latest brain-inspired AI efforts using cloned structured probabilistic graph models to develop an account of how the hippocampus makes a model of the world and represents our cognitive maps in different contexts, so we can simulate possible outcomes to choose how to act.

Special guest questions from Brad Love (episode 70: How We Learn Concepts) .

• Vicarious website - Dileep's AGI robotics company.
• Twitter: @dileeplearning.
• Papers we discuss:
  • Learning cognitive maps as structured graphs for vicarious evaluation.
  • A detailed mathematical theory of thalamic and cortical microcircuits based on inference in a generative vision model.
• Probabilistic graphical models.
• Hierarchical temporal memory.
