Information Theory Notes
... 0101110. If the 4-symbol channel has no noise, then we could send 2 bits of information per transmission by using the following scheme: Block the inputs two bits at a time: 01, 01, 11, 10, and send the messages 1, 1, 3, 2, across the channel. Then the channel decoder inverts back to 01, 01, 11, 10 a ...

... We will let P n (i, j) denote the (i, j) element in the matrix P n . ⊲ Exercise [1.7] gives some basic practice with the definitions. So, in principle, we can find the answer to any question about the probabilistic behavior of a Markov chain by doing matrix algebra, finding powers of matrices, etc. ...

Arbitrarily large randomness distillation

Preference-based belief operators

In a semantic formulation of belief operators one can, following Aumann (1999), start with an information partition of W, and then assume that the decision maker, for each element of the partition, is endowed with a probability distribution that is concentrated on this element of the partition.

Sets of Probability Distributions and Independence

For instance we can have vacuous credal sets K(X|Y = y) for every y, and still K(X) can be a non-vacuous credal set (even a singleton5 ). It seems bizarre to say that Y is then irrelevant to X.
