DENSITY CONSCIOUS SUBSPACE CLUSTERING USING ITL DATA STRUCTURE [PDF]

ICTACT Journal on Soft Computing, 2011
Most of the subspace clustering algorithms uses monotonicity property to generate higher dimensional subspaces. But this property is not applicable here since different subspace cardinalities have varying densities i.e., if a k-dimensional unit is dense,

Subspace Methods in System Identification

IFAC Proceedings Volumes, 1994
Abstract Subspace-based methods for system identification have attracted much attention during the past few years. This interest is due to the ability of providing accurate state-space models for multivariable linear systems directly from input-output data.

Multivariate Identification via Linear Projection of Eigenvectors

Mathematics
A data-driven system identification algorithm that utilizes eigenvectors is presented. The eigenvectors are extracted from a unified solution space comprising both input and output subspaces. To expand the input subspace, a higher-order subspace from the

Modal–Physical Hybrid System Identification of High-rise Building via Subspace and Inverse-Mode Methods

Frontiers in Built Environment, 2017
A system identification (SI) problem of high-rise buildings is investigated under restricted data environments. The shear and bending stiffnesses of a shear-bending model (SB model) representing the high-rise buildings are identified via the smart ...
