A decision boundary is the region of a problem space in which the output label of a classifier is ambiguous. [1] If the decision surface is a hyperplane, then the classification problem is linear, and the classes are linearly separable . Decision boundaries are not always clear cut. That is, the transition from one class in the feature space to ...
The weighted average cost of capital ( WACC) is the rate that a company is expected to pay on average to all its security holders to finance its assets. The WACC is commonly referred to as the firm's cost of capital. Importantly, it is dictated by the external market and not by management. The WACC represents the minimum return that a company ...
Weighted sum model. In decision theory, the weighted sum model ( WSM ), [1] [2] also called weighted linear combination ( WLC) [3] or simple additive weighting ( SAW ), [4] is the best known and simplest multi-criteria decision analysis (MCDA) / multi-criteria decision making method for evaluating a number of alternatives in terms of a number ...
The Sumatran tiger has a weight of 100–140 kg (220–310 lb) for males and 75–110 kg (165–243 lb) for females. The extinct Bali tiger was even smaller. Coat Tiger coat. The tiger's coat usually has short hairs, reaching up to 35 mm (1.4 in), though the hairs of the northern-living Siberian tiger can reach 105 mm (4.1 in).
The expected utility hypothesis is a foundational assumption in mathematical economics concerning decision making under uncertainty. It postulates that rational agents maximize utility, meaning the subjective desirability of their actions. Rational choice theory, a cornerstone of microeconomics, builds this postulate to model aggregate social ...
e. Accounting, also known as accountancy, is the process of recording and processing information about economic entities, such as businesses and corporations. [1] [2] Accounting measures the results of an organization's economic activities and conveys this information to a variety of stakeholders, including investors, creditors, management, and ...
Encephalization quotient ( EQ ), encephalization level ( EL ), or just encephalization is a relative brain size measure that is defined as the ratio between observed and predicted brain mass for an animal of a given size, based on nonlinear regression on a range of reference species. [1] [2] It has been used as a proxy for intelligence and thus ...
Lever rule. In chemistry, the lever rule is a formula used to determine the mole fraction ( xi) or the mass fraction ( wi) of each phase of a binary equilibrium phase diagram. It can be used to determine the fraction of liquid and solid phases for a given binary composition and temperature that is between the liquidus and solidus line.
