conditional mutual informationの例文
- relating the conditional expectation to the conditional mutual information.
- This is a simple consequence of Pinsker's inequality . ( Note : the correction factor log 2 inside the radical arises because we are measuring the conditional mutual information in bits rather than nats .)
- where, for example, I ( X; Y ) is the mutual information between variables X and Y, and I ( X; Y | Z ) is the conditional mutual information between variables X and Y given Z.
- In such cases, the positive conditional mutual information between the plaintext and ciphertext ( conditioned on the key ) can ensure proper transmission, while the unconditional mutual information between the plaintext and ciphertext remains zero, resulting in absolutely secure communications.
- In probability theory, and in particular, information theory, the "'conditional mutual information "'is, in its most basic form, the expected value of the mutual information of two random variables given the value of a third.
