When there is large variance in information, how are we in terms of what’s going to happen? What does this cause?
We are ignorant about what’s going to happen. Causes us to get lots of information when we make an observation
When there is small variance in information, how are we in terms of what’s going to happen? What does this cause?
We know how our observation turns out therefore little information from making the observation
The measure of transmitted info is a measure of…
The input-output correlation
What does the asymptotic value represent?
Channel capacity of the observer
