What is Consciousness

Posted on Edited on In , ,

1. Question

Real me? Self?

How idea create?

Model of brain? computational, logical (lead to un-logical mind??)

What I real want to do? Understand how brain works

2. Thoughts

David Edelman, creation of Conscious Artifact

  • Reentrant Architecture

Different than feedback system.

Bi-directionally linked, physical

  • Thalamo-Cortical System

Dynamic core

  • Value system, reinforcement

For an agent to modify its behavior

  • Phenotype

Shape, morphology of the robot. Touch is important

  • Motor control

Motor command is fed back to nervous system

Basal Ganglia

  • Learning and momory. Very complicated model

  • Problem: how to transfer knowledge to other task

  • Communication, not language, but showing a degree of self-awareness

  • Thought

Dynamic core theory

  • Language: language is distinctively more sophisticated

2006, UCI, “Build A Brain” meeting

3. Todo

Theory of Neuronal Group Selection

4. Common Sense

Computational model for common sense

Current AI: just pattern recognition, function approximation

Gap: model the world, explain, image, plan, build, share

Self-driving car:

  • cost: 100 billion,
  • not close to solution
  • long-tail problem

Common sense enable flexiable behavior

  • understanding the world
  • agents have their goal and plan
  • abstract of knowledge about
  • Physics, motion, force
  • Psychology, belief, plan

Smart: learn quickly from example

  • Understand others’ goal
  • Have a plan
  • Trying to help

Starting state: a core cognition, game engine

  • learning procedure is very smart

Reverse Engineering

How? Build based on DL platform (TF, PyTorch)

Probabilistic programs

  • Symbolic manipulation, enable the auto back prop for super large NN
  • Bayesian inference, reasoning in uncertain situation
  • Neural network good for pattern recognition and function approximation

We need a fast and good (not perfect) simulator

What to learn?

How to learn?

Intuitive physics

  • train a network to inverse guess from the vision to 3d world

Intuitive psychology

What to learn?

  • Program to program new

5. Build a Brain

Deep down

Spaun

  • see
  • remember
  • act

Understand the neuron (single, multiple)
