Knowledge and Uncertainty Flashcards
What are maximally informative questions?
The most informative questions, which are the ones whose answer we are the most uncertain about.
What do you need to do when evaluating a question?
We need to consider both possible answer: “yes” and “no
How can we quantify uncertainty?
By counting the number of maximally informative questions required to resolve our lack of knowledge.
What happens every time you double the number of possibilities?
You increase the missing information by one bit.
What are maximally informative questions also known as?
Bits (ex. if a situation requires 3 bits to find the answer, you need to ask a minimum of 3 maximally informative questions to find the answer.
If suspect i has probability pᵢ of being the criminal, then what is the relationship between the amount of missing information and the probability that they’re the criminal?
pᵢ = 1/2^(missing information).
