Physics-Guided Neural Networks for Feedforward Control: An Orthogonal Projection-Based Approach [PDF]
American Control Conference, 2022 Unknown nonlinear dynamics can limit the performance of model-based feedforward control. The aim of this paper is to develop a feedforward control framework for systems with unknown, typically nonlinear, dynamics.

Orthogonal Discriminant Diversity and Similarity Preserving Projection for Face Recognition
MATEC Web of Conferences, 2016 Feature extraction is a crucial step for face recognition. In this paper, based on supervised local structure and diversity projection (SLSDP), a new feature extraction method called orthogonal discriminant diversity and similarity preserving projection (

On the uniqueness of minimal projections in Banach spaces [PDF]
Opuscula Mathematica, 2012 Let \(X\) be a uniformly convex Banach space with a continuous semi-inner product. We investigate the relation of orthogonality in \(X\) and generalized projections acting on \(X\). We prove uniqueness of orthogonal and co-orthogonal projections.

Orthogonal and projected orthogonal matched filter detection [PDF]
Signal Processing, 2004 This paper considers the genetic problem of detecting in the presence of additive noise, which one from a set of known signals has been received. In place of the classical matched filter (MF) receiver we propose a modified receiver. When the transmitted signals are linearly independent this receiver is referred to as an orthogonal matched filter (OMF ...

PCA-SRGAN: Incremental Orthogonal Projection Discrimination for Face Super-resolution [PDF]
ACM Multimedia, 2020 Generative Adversarial Networks (GANs) have been employed for face super resolution but they bring distorted facial details easily and still have weakness on recovering realistic texture.

Reconstruction of helices from their orthogonal projection
Computer Aided Geometric Design, 2016 We describe a method for modeling helices from planar curves. Given a polygonal curve in the ( x , y ) plane, the method computes a helix such that its orthogonal projection onto the ( x , y ) plane fits the polygonal curve.

Duals of Some Constructed $*$-Frames by Equivalent $*$-Frames [PDF]
Sahand Communications in Mathematical Analysis, 2019 Hilbert frames theory have been extended to frames in Hilbert $C^*$-modules. The paper introduces equivalent $*$-frames and presents ordinary duals of a constructed $*$-frame by an adjointable and invertible operator.

Low-Rank and Sparse Decomposition of Compressive Sensing Observation Signals [PDF]
Jisuanji gongcheng, 2022 Low-rank and sparse decomposition can be used in video surveillance analysis.This composition is more difficult to perform on Compressive Sensing(CS) videos than on videos sampled by the Nyquist theorem.Inspired by the method of projecting Nyquist ...

Spectral approximation methods for Fredholm integral equations with non-smooth kernels
Mathematical Modelling and Analysis, 2022 In this paper, polynomially based projection and modified projection methods for approximating the solution of Fredholm integral equations with a kernel of Green’s function type are studied.
