  2. Value of information - Wikipedia

    en.wikipedia.org/wiki/Value_of_information

    The value of information can never be less than zero since the decision-maker can always ignore the additional information and make a decision as if such information is not available. No other information gathering/sharing activities can be more valuable than that quantified by value of clairvoyance.

  3. Data valuation - Wikipedia

    en.wikipedia.org/wiki/Data_valuation

    The data value metric (DVM) quantifies the useful information content of large and heterogeneous datasets in terms of the tradeoffs between the size, utility, value, and energy of the data. [13] Such methods can be used to determine if appending, expanding, or augmenting an existent dataset may improve the modeling or understanding of the ...

  4. Expected value of sample information - Wikipedia

    en.wikipedia.org/wiki/Expected_value_of_sample...

    The expected value of including uncertainty (EVIU) compares the value of modeling uncertain information as compared to modeling a situation without taking uncertainty into account. Since the impact of uncertainty on computed results is often analysed using Monte Carlo methods, EVIU appears to be very similar to the value of carrying out an ...

  5. Fisher information - Wikipedia

    en.wikipedia.org/wiki/Fisher_information

    Fisher information is widely used in optimal experimental design. Because of the reciprocity of estimator-variance and Fisher information, minimizing the variance corresponds to maximizing the information. When the linear (or linearized) statistical model has several parameters, the mean of the parameter estimator is a vector and its variance ...

  6. Entropy (information theory) - Wikipedia

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

    The information gain in decision trees (,), which is equal to the difference between the entropy of and the conditional entropy of given , quantifies the expected information, or the reduction in entropy, from additionally knowing the value of an attribute . The information gain is used to identify which attributes of the dataset provide the ...

  9. Information economics - Wikipedia

    en.wikipedia.org/wiki/Information_economics

    Information economics or the economics of information is the branch of microeconomics that studies how information and information systems affect an economy and economic decisions. [ 1 ] One application considers information embodied in certain types of commodities that are "expensive to produce but cheap to reproduce."
