  2. Profit maximization - Wikipedia

    en.wikipedia.org/wiki/Profit_maximization

    The optimal output, shown in the graph as , is the level of output at which marginal cost equals marginal revenue. The price that induces that quantity of output is the height of the demand curve at that quantity (denoted P m {\displaystyle P_{m}} ).

  3. Yerkes–Dodson law - Wikipedia

    en.wikipedia.org/wiki/Yerkes–Dodson_law

    Researchers have found that different tasks require different levels of arousal for optimal performance. For example, difficult or intellectually demanding tasks may require a lower level of arousal (to facilitate concentration), whereas tasks demanding stamina or persistence may be performed better with higher levels of arousal (to increase motivation).

  4. Line chart - Wikipedia

    en.wikipedia.org/wiki/Line_chart

    Line chart showing the population of the town of Pushkin, Saint Petersburg from 1800 to 2010, measured at various intervals. A line chart or line graph, also known as curve chart, [1] is a type of chart that displays information as a series of data points called 'markers' connected by straight line segments. [2]

  5. Optimality theory - Wikipedia

    en.wikipedia.org/wiki/Optimality_Theory

    Evaluator (Eval) chooses the optimal candidate based on the constraints, and this candidate is the output. Optimality theory assumes that these components are universal. Differences in grammars reflect different rankings of the universal constraint set, Con .

  7. Receiver operating characteristic - Wikipedia

    en.wikipedia.org/wiki/Receiver_operating...

    A classification model (classifier or diagnosis [7]) is a mapping of instances between certain classes/groups.Because the classifier or diagnosis result can be an arbitrary real value (continuous output), the classifier boundary between classes must be determined by a threshold value (for instance, to determine whether a person has hypertension based on a blood pressure measure).

  8. Statistical graphics - Wikipedia

    en.wikipedia.org/wiki/Statistical_graphics

    Statistical graphics have been central to the development of science and date to the earliest attempts to analyse data. Many familiar forms, including bivariate plots, statistical maps, bar charts, and coordinate paper were used in the 18th century. Statistical graphics developed through attention to four problems: [3]

  9. Bellman equation - Wikipedia

    en.wikipedia.org/wiki/Bellman_equation

    The relationship between these two value functions is called the "Bellman equation". In this approach, the optimal policy in the last time period is specified in advance as a function of the state variable's value at that time, and the resulting optimal value of the objective function is thus expressed in terms of that value of the state variable.
