Adjacency Spectral Embedding (ASE)
Description
ase
calculates the -dimensional adjacency spectral embedding of a symmetric
matrix
.
Usage
ase(M,d)
Arguments
M |
A symmetric matrix. |
d |
A non-negative integer embedding dimension. |
Value
An matrix
, defined as
where
is a diagonal matrix of the
leading (in absolute value)
eigenvalues of
, and
is a matrix of the corresponding
eigenvectors.
has an additional attribute
"signs"
which gives the sign of
the eigenvalue corresponding to each column.
If ,
ase
returns an
matrix of zeros.
