  2. Entropy (information theory) - Wikipedia

    en.wikipedia.org/wiki/Entropy_(information_theory)

    The entropy of the unknown result of the next toss of the coin is maximized if the coin is fair (that is, if heads and tails both have equal probability 1/2). This is the situation of maximum uncertainty as it is most difficult to predict the outcome of the next toss; the result of each toss of the coin delivers one full bit of information.

  3. List of Source mods - Wikipedia

    The game is primarily set in the Iraq war, however some maps are set in Afghanistan, and future updates are planned to expand the setting into a hypothetical conflict in Kosovo and other theatres. Insurgency received the Player's Choice 2007 "Mod of the Year" award from ModDB, [56] as well as the "Best Source Mod of 2007" Gold Award from ...

  4. CMB cold spot - Wikipedia

    en.wikipedia.org/wiki/CMB_cold_spot

    One possible explanation of the cold spot is a huge void between us and the primordial CMB. A region cooler than surrounding sightlines can be observed if a large void is present, as such a void would cause an increased cancellation between the "late-time" integrated Sachs–Wolfe effect and the "ordinary" Sachs–Wolfe effect. [10]

  5. Full entropy - Wikipedia

    en.wikipedia.org/wiki/Full_entropy

    The ideal elements by nature have an entropy value of n. The inputs of the conditioning function will need to have a higher min-entropy value H to satisfy the full-entropy definition. The number of additional bits of entropy depends on W and δ; the following table contains few representative values: [4]

  6. Entropy in thermodynamics and information theory - Wikipedia

    Despite the foregoing, there is a difference between the two quantities. The information entropy Η can be calculated for any probability distribution (if the "message" is taken to be that the event i which had probability p i occurred, out of the space of the events possible), while the thermodynamic entropy S refers to thermodynamic probabilities p i specifically.

  7. Logistic map - Wikipedia

    en.wikipedia.org/wiki/Logistic_map

    Both the logistic map and the sine map are one-dimensional maps that map the interval [0, 1] to [0, 1] and satisfy the following property, called unimodal . = =. The map is differentiable and there exists a unique critical point c in [0, 1] such that ′ =. In general, if a one-dimensional map with one parameter and one variable is unimodal and ...

  8. Information theory - Wikipedia

    en.wikipedia.org/wiki/Information_theory

    (Here, I(x) is the self-information, which is the entropy contribution of an individual message, and is the expected value.) A property of entropy is that it is maximized when all the messages in the message space are equiprobable p(x) = 1/n; i.e., most unpredictable, in which case H(X) = log n.

  9. Local Void - Wikipedia

    en.wikipedia.org/wiki/Local_Void

    The Local Void is a vast, empty region of space, lying adjacent to the Local Group. [ 3 ] [ 4 ] Discovered by Brent Tully and Rick Fisher in 1987, [ 5 ] the Local Void is now known to be composed of three separate sectors, separated by bridges of "wispy filaments ". [ 4 ]
