Archives of Acoustics, 2016 Subspace-based methods have been effectively used to estimate enhanced speech from noisy speech samples. In the traditional subspace approaches, a critical step is splitting of two invariant subspaces associated with signal and noise via subspace ...

MEG source localization using invariance of noise space.
PLoS ONE, 2013 We propose INvariance of Noise (INN) space as a novel method for source localization of magnetoencephalography (MEG) data. The method is based on the fact that modulations of source strengths across time change the energy in signal subspace but leave the

Pivot-Guided Embedding for Domain Generalization
IEEE Access, 2022 Neural networks have suffered from a distribution gap between training and test data, known as domain shift. Domain generalization (DG) methods aim to learn domain invariant representations only with limited source domain data to cope with unseen target ...

Transformation invariance in hand shape recognition [PDF]
, 2006 In hand shape recognition, transformation invariance is key for successful recognition. We propose a system that is invariant to small scale, translation and shape variations.

Simultaneous Multislice Brain MRI T1 Mapping with Improved Low-Rank Modeling
Tomography, 2021 To accelerate data acquisition speed in magnetic resonance imaging (MRI), multiple slices are simultaneously acquired using multiband pulses. Simultaneous multislice (SMS) imaging typically unfolds slice aliasing from the acquired collapsed slices.

New observations on invariant subspace attack [PDF]
, 2018 © 2018 Elsevier B.V. Invariant subspace attack is a novel cryptanalytic technique which breaks several recently proposed lightweight block ciphers. In this paper, we propose a new method to bound the dimension of some invariant subspaces in a class of ...

Robust Gridless Estimation of Angles and Delays for Full-Dimensional Wideband mmWave Channels
IEEE Open Journal of Signal Processing, 2023 In this paper, we consider robust channel estimation for a millimeter wave (mmWave) massive MIMO system with uniform planar arrays (UPA). For many gridless angle estimation methods of mmWave channels, the channel gains needs to be time-invariant during ...

Tracking directions-of-arrival with invariant subspace updating [PDF]
, 1996 A new method for solving directions-of-arrival (DOA) tracking problems is presented. It is based on a practical method for updating invariant subspaces, introduced by G.W. Stewart. This method is O(L2), where L is the number of array sensors.

A new method for constructing invariant subspaces
Journal of Mathematical Analysis and Applications, 2007 The method of compatible sequences is introduced in order to produce non-trivial (closed) invariant subspaces of (bounded linear) operators. Also a topological tool is used which is new in the search of invariant subspaces: the extraction of continuous selections of lower semicontinuous set valued functions. The advantage of this method over previously
