Application of Orthogonal Polynomial in Orthogonal Projection of Algebraic Surface

open access: yesAxioms, 2022
Point orthogonal projection onto an algebraic surface is a very important topic in computer-aided geometric design and other fields. However, implementing this method is currently extremely challenging and difficult because it is difficult to achieve to ...

Orthogonal Projection Loss [PDF]

open access: yes2021 IEEE/CVF International Conference on Computer Vision (ICCV), 2021
Deep neural networks have achieved remarkable performance on a range of classification tasks, with softmax cross-entropy (CE) loss emerging as the de-facto objective function. The CE loss encourages features of a class to have a higher projection score on the true class-vector compared to the negative classes. However, this is a relative constraint and

An enhanced text classification model by the inverted attention orthogonal projection module

open access: yesConnection Science, 2023
The orthogonal projection method has made significant progress in text classification, especially in generating discriminative features. This method obtains more pure and suitable for classification features by projecting text features onto the ...

On the uniqueness of minimal projections in Banach spaces [PDF]

open access: yesOpuscula 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.

Restricted orthogonal gradient projection for continual learning

open access: yesAI Open, 2023
Continual learning aims to avoid catastrophic forgetting and effectively leverage learned experiences to master new knowledge. Existing gradient projection approaches impose hard constraints on the optimization space for new tasks to minimize ...

Orthogonal and projected orthogonal matched filter detection [PDF]

open access: yesSignal 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 ...

Duals of Some Constructed $*$-Frames by Equivalent $*$-Frames [PDF]

open access: yesSahand 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]

open access: yesJisuanji 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

open access: yesMathematical 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.
