The majorization between the eigenvalues and the diagonal entries of a symmetric matrix is proved. Majorization for integer vectors is considered and the necessity part of the theorem of Gale and Ryser is proved. Threshold graphs are defined in the next section. It is proved that a graph is ...
Here \xi are the polarization vectors. Integrated Ward identity \langle (\partial \cdot J_{\ell}) \Phi_1(x_1)\ldots \Phi_n (x_n) \rangle \propto\sum_{k=1}^n\delta(y - x_{k})\langle \Phi_1(x_1)\ldots [Q(\xi), \Phi_k(x_k)]\ldots \Phi_n(x_n) \rangle, ...
In case of a standard form vN-algebra, the Bures distance is the natural distance between the fibres of implementing vectors at normal positive linear forms. Thereby, it is well-known that to each two normal positive linear forms implementing vectors exist such that the Bures distance is ...
In this lesson we use Pythagoras' theorem and right triangles to develop an equation to find the distance between any two points in a...
Given two binary vectors 𝐱,𝐲∈{0,1}𝑛, vectors 𝐱 and y are encoded as x ′ and y ′ ∈ { − 1 , 1 } n by changing the zeroes in x and y to − 1 . Subsequently, the Hamming distance between x and y is d ( x , y ) = n − 〈 x ′ , y ′ 〉 /...
The naive implementation benefits from fast software such as the Julia Distances package, which exploits matrix multiplication to find all Euclidean distances between the column vectors of two matrices. The ImageDistances.jl package (github.com/JuliaImages/Images.jl) appears to rely on the naive ...
The Pearson distance is a correlation distance based on Pearson's product-momentum correlation coefficient of the two sample vectors. Since the correlation coefficient falls between [-1, 1], the Pearson distance lies in [0, 2] and measures the linear relationship between the two vectors. ...
The ||mu_1 – mu_2||^2 refers to the sum squared difference between the two mean vectors. Tr refers to the trace linear algebra operation, e.g. the sum of the elements along the main diagonal of the square matrix. The sqrt is the square root of the square matrix, ...
median correlationbetween two 1d sets of the same length. We define this correlation similarly to Pearson, as cosine of an angle between two normalised samples, interpreted as coordinate vectors. Pearson first normalises each set by subtracting its mean from all components. Whereas we subtract the...
