Semi-orthogonal matrix
WebThis is an unofficial re-implementation of the paper Semi-orthogonal Embedding for Efficient Unsupervised Anomaly Segmentation [1] available on arxiv.This paper proposes a modification on the PaDiM [2] method, mainly to replace the random dimension selection with an optimized inverse covariance computation using a semi-orthogonal embedding. WebIn linear algebra, a semi-orthogonal matrix is a non-square matrix with real entries where: if the number of columns exceeds the number of rows, then the rows are orthonormal vectors; but if the number of rows exceeds the number of columns, then the columns are …

WebIn linear algebra, a semi-orthogonal matrix is a non-square matrix with real entries where: if the number of columns exceeds the number of rows, then the rows are orthonormal vectors; but if the number of rows exceeds the number of columns, then the columns are orthonormal vectors. WebAn improper rotation matrix is an orthogonal matrix, R, such that det R = −1. The most general three-dimensional improper rotation, denoted by R(nˆ,θ), consists of a product of a proper rotation matrix, R(nˆ,θ), and a mirror reflection through a plane normal to the unit vector nˆ, which we denote by R(nˆ). In particular, the ...
WebWe introduce a factored form of TDNNs (TDNN-F) which is structurally the same as a TDNN whose layers have been compressed via SVD, but is trained from a random start with one of the two factors of each matrix constrained to be semi-orthogonal. This gives substantial improvements over TDNNs and performs about as well as TDNN-LSTM hybrids.
