1.a diagram representing a system of connections or interrelations among two or more things, as by a number of distinctive dots or lines. 2.Math. a.a series of discrete or continuous points, as in forming a curve or surface, each of which represents a value of a given function. ...
Two applications of FDGs are presented: in the former, FDGs are used for modelling and matching 3D-objects described by multiple views, whereas in the latter, they are used for representing and recognising human faces, described also by several views....
In this notation, the symbol f represents the function, the letter x is the independent variable(自变量) representing the input value of f, and y is the dependent variable(因变量) or output value of f at x. The set D of all possible input values is called the domain(定义域) of the ...
Also known as Mekko charts, these are not found commonly because we often use them for representing different complex data. You can use it to compare multiple categories or variables at the same time. These also come in handy if the variables aren’t numeric, like the look, feel, sound, ...
Using Function NotationOnce we determine that a relationship is a function, we need to display and define the functional relationships so that we can understand and use them, and sometimes also so that we can program them into computers. There are various ways of representing fun...
This construction, a plane plus two perpendicular axes, is called a cartesian plane (named after René Decartes, 1596 - 1650). If we draw points on a cartesian plane or if we draw a curve representing a function on a cartesian plane then we say that we are graphing or drawing a ...
The vertex can be found from an equation representing a quadratic function. The domain of a quadratic function is all real numbers. The range varies with the function. Glossary axis of symmetry a vertical line drawn through the vertex of a parabola around which the parabola is symmetric; it ...
where is a small parameter (representing the discretised time step), now takes values in the integer multiples of , and is the wave propagator operator or the heat propagator (the two operators are different, but agree to fourth order in ). One can then formally verify that the wave equat...
This graph can be understood, for instance, as a model for information diffusion in a social network or as representing a specific type of neurological connections in a biological system. Information originates from any vertex on the lower line and propagates through the network, advancing one st...
Air-USA is a dataset made up of graphs representing airport traffic within the US. Each node represents an airport and edges between nodes indicate the existence of commercial flights between the two airports (Wu, He, & Xu, 2019). – BlogCatalog and Flickr are both social network datasets, ...
