• Weak AI - solving hard problems. State of art.
• AI - a machine can understand problems. (Classical problem of Chinese room)

How to cope with uncertainty?

• Act as in believe state.
• We eliminated some states by performing actions.
• Big problem of large number of n states.
• Trying can explore actions by going to \(2^n\) (I can use 2 actions from one state)
• Apriorni pravděpodobnost (?aprior probability?) – unconditional probability
• Příklad: \(P(Cavity \mid toothache) = \alpha\)
• Nezavislost nam umoznuje ukladat mensi tabulky pro vypocet marginalni pravdepodobnosti.
• Podminena nezavislost je castejsi a take setri \(P(X \mid Y,Z) = P(X \mid Y)*P(X \mid Z)\) vypocet
