Matplotlib (portmanteau of MATLAB, plot, and library [3]) is a plotting library for the Python programming language and its numerical mathematics extension NumPy.It provides an object-oriented API for embedding plots into applications using general-purpose GUI toolkits like Tkinter, wxPython, Qt, or GTK.
UpSet plots are a data visualization method for showing set data with more than three intersecting sets. UpSet shows intersections in a matrix, with the rows of the matrix corresponding to the sets, and the columns to the intersections between these sets (or vice versa). The size of the sets and of the intersections are shown as bar charts.
Flattening is a measure of the compression of a circle or sphere along a diameter to form an ellipse or an ellipsoid of revolution respectively. Other terms used are ellipticity , or oblateness . The usual notation for flattening is f {\displaystyle f} and its definition in terms of the semi-axes a {\displaystyle a} and b {\displaystyle b} of ...
In particular, a function is called non-monotone if it has the property that adding more elements to a set can decrease the value of the function. More formally, the function f {\displaystyle f} is non-monotone if there are sets S , T {\displaystyle S,T} in its domain s.t. S ⊂ T {\displaystyle S\subset T} and f ( S ) > f ( T ) {\displaystyle ...
A function that is flat at is not analytic at unless it is constant in a neighbourhood of (since an analytic function must equals the sum of its Taylor series). An example of a flat function at 0 is the function such that f ( 0 ) = 0 {\displaystyle f(0)=0} and f ( x ) = e − 1 / x 2 {\textstyle f(x)=e^{-1/x^{2}}} for x ≠ 0. {\displaystyle x ...
where = is the subset of nodes with the top-k highest projection scores, denotes element-wise matrix multiplication, and () is the sigmoid function. In other words, the nodes with the top-k highest projection scores are retained in the new adjacency matrix A ′ {\displaystyle \mathbf {A} '} .
A wide variety of sigmoid functions including the logistic and hyperbolic tangent functions have been used as the activation function of artificial neurons. Sigmoid curves are also common in statistics as cumulative distribution functions (which go from 0 to 1), such as the integrals of the logistic density , the normal density , and Student's ...
The lower contour set of is the set of all such that is related to them: { y ∍ x ≽ y } {\displaystyle \left\{y~\backepsilon ~x\succcurlyeq y\right\}} The strict upper contour set of x {\displaystyle x} is the set of all y {\displaystyle y} that are related to x {\displaystyle x} without x {\displaystyle x} being in this way related to any ...
