  2. Aggregate function - Wikipedia

    en.wikipedia.org/wiki/Aggregate_function

    Aggregate functions present a bottleneck, because they potentially require having all input values at once.In distributed computing, it is desirable to divide such computations into smaller pieces, and distribute the work, usually computing in parallel, via a divide and conquer algorithm.

  3. Fold (higher-order function) - Wikipedia

    en.wikipedia.org/wiki/Fold_(higher-order_function)

    In functional programming, fold (also termed reduce, accumulate, aggregate, compress, or inject) refers to a family of higher-order functions that analyze a recursive data structure and through use of a given combining operation, recombine the results of recursively processing its constituent parts, building up a return value.

  4. Aggregate - Wikipedia

    en.wikipedia.org/wiki/Aggregate

    Aggregate function, aggregation function, in database management is a function wherein the values of multiple rows are grouped together to form a single summary value Aggregate Level Simulation Protocol (ALSP), a protocol and supporting software that enables simulations to interoperate with one another

  5. Aggregation - Wikipedia

    en.wikipedia.org/wiki/Aggregation

    Aggregate function, a type of function in data processing; Aggregation, a form of object composition in object-oriented programming; Link aggregation, using multiple Ethernet network cables/ports in parallel to increase link speed; Packet aggregation, joining multiple data packets for transmission as a single unit to increase network efficiency

  6. Production function - Wikipedia

    en.wikipedia.org/wiki/Production_function

    In macroeconomics, aggregate production functions for whole nations are sometimes constructed. In theory, they are the summation of all the production functions of individual producers; however there are methodological problems associated with aggregate production functions, and economists have debated extensively whether the concept is valid. [3]

  7. Aggregation problem - Wikipedia

    en.wikipedia.org/wiki/Aggregation_problem

    Sonnenschein-Mantel-Debreu theorem (SMD theorem) is a theorem for exchange economy that can be expressed in the following way: . for a function that is continuous, homogeneous of degree zero, and in accord with Walras's law,there is an economy with at least as many agents as goods such that, for prices bounded away from zero, the function is the aggregate demand function for this economy.

  8. Lucas aggregate supply function - Wikipedia

    en.wikipedia.org/.../Lucas_aggregate_supply_function

    The Lucas aggregate supply function or Lucas "surprise" supply function, based on the Lucas imperfect information model, is a representation of aggregate supply based on the work of new classical economist Robert Lucas. The model states that economic output is a function of money or price "surprise".

  9. Convolution of probability distributions - Wikipedia

    en.wikipedia.org/wiki/Convolution_of_probability...

    The probability distribution of the sum of two or more independent random variables is the convolution of their individual distributions. The term is motivated by the fact that the probability mass function or probability density function of a sum of independent random variables is the convolution of their corresponding probability mass functions or probability density functions respectively.
