29.40. Fads in AI
- Reinforcement Learning = Deficient in Credit Assignment
- Rule-Based Systems = Limited Representation
- Neural Networks = Opague to Reflective Thinking
- Statistical Inference = Fails to use Causal Reasoning
- Formal Logic = Cannot exploit analogies
- Genetic Programs = Fail to remember the causes of failures
- Insect-like Robots = These projects just re-create previous ones.
- Baby Machines = All have failed to develop high level thinking
But each method works only in certain domains. We need to know both when each method works and why it fails.
30 & 31. Jerry Sussman and Hal Ablenson
One program to use an AI working to solve the problem.
43.17. A "Critic-Selector" Theory of Brain
Suppose you fail to achieve a goal or your thinking gets stuck in some other way. Then your brain uses special machinery to (1) diagnose what went wrong and (2) activate some more appropriate Way to Think.
Recognize a Problem-Type >> Activate a "Way to Think"
CRITICS / SELECTORS
If a problem seems familier, try reasoning by Analogy. If it seems unfamilier, change how your describing it. If it still seems too difficult, divide it into several parts. If a problem is too complex, replace it by a simpler one. If your methods do not work, ask someone else for help.
51.23. Old vs. new views of emotion
Old view of Emotion: Emotional states augment our mind the way artists add colors to black and white drawings.
New view of Emotions : Each emotional state suppresses certain features of regular thinking.
