Orthogonal Projection Loss(正交投影损失) 深度神经网络在一系列分类任务上均取得了卓越的性能,其中出现了softmax交叉熵(CE)损失,成为事实上的目标函数。 CE丧失鼓励班级的特征与真实类别向量相比,投影得分更高否定的阶级。但是,这是一个相对的约束并没有明确强制将不同的类特征设置为分开的。通过观察CE损失中的地面...
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 ...
Orthogonal LoRA缓解遗忘是指的多个领域的LoRA之间缓解,其实并不能缓解模型内部知识的遗忘,因为第一个LoRA训练的时候,就会导致模型内部知识遗忘,那有没有什么方法可以让第一个LoRA训练的时候使得模型不遗忘呢,我提出Orthogonal Loss来解决这个问题。 得益于《Gradient Projection Memory for Continual Learning》和Orthogonal ...
Projections and projection matrices/operators play a crucial part in machine learning, signal processing, and optimization in general; after all, a projection corresponds to a minimization task when the loss is interpreted as a “distance.” Let A be an l×k,k<l, matrix with column vectors, ...

, and then analyzing the orthogonal projection onto F. The formula for the orthogonal projection is shown to be simple and easy to integrate into the traditional neural model. This projection concept was first developed by Wolfe et al. (1993), but here we show that the projection can be com...
Projection of the HNT34 signature onto the LINCS L100021 dataset space demonstrated that transcriptional changes associated with an EVI1 “Off” status mimic and match HDACis signatures (Fig. 1F, Supplementary Fig. 2F, G and Supplementary Data 1). The suppression of an EVI1-transcriptional ...
The orthogonal subspace projection (OSP) operator can be extended to k-signatures of interest, thus reducing the dimensionality of k and classifying the hyperspectral image simultaneously. The approach is applicable to both spectrally pure as well as mixed pixels. 展开 ...
The performance loss comes from increased inter carrier interference (ICI), associated with the loss of orthogonality, when spectral resources are densely compressed. Here, even the optimal ML signal detector can not recover signals. This work therefore aims to explore the challenge and propose new ...
