为了解决FSDLRE中的两个问题,本文提出了一种新颖的关系感知原型学习方法(Relation-Aware Prototype Learning method,RAPL)。首先,对于支持文档中存在关系的每一对实体,利用关系描述中的固有关系语义作为指导,为每一个表达的关系生成一个实例级别的表示,如图2(b)所示。关系原型是通过聚合所有支持关系实例的表示来构建的,...
The overall framework, namely as Prototype-aware Contrastive learning (ProCo), is unified as a single-stage pipeline in an end-to-end manner to alleviate the imbalanced problem in medical image classification, which is also a distinct progress than existing works as they follow the traditional ...
(e.g., daily and seasonal changes). This can render those short-term strategies suboptimal or even obsolete when performing continuous AVC over extended periods. In this paper, we propose a novel temporal prototype-aware learning method, abbreviated as TPA, to learn time-adaptive AVC under ...
在DG的问题中,需要去把学习到的语义结构信息泛化到目标域上。于是,文章提出了两个模块Prototypical Graph Reasoning (ProtoGR)和Prototypical Category-aware Contrastive Learning (ProtoCCL)。 ProtoGR帮助每一类的原型去推理(attend and reason)其邻域的原型特征,这样可以捕获语义结构的拓扑信息。ProtoCCL则是通过对比...
在Domain Adaptive Object Detection 的领域背景下(就是把UDA任务放到目标检测上),一类常用的做法是利用大量的region proposal建模prototype,进一步根据metric learning实现prototype-based的对齐(数据层次= bounding box,定义方式=特征均值/graph aggregation,更新方式=online,下游任务=域对齐 )。通过对不同类的prototype建模...
论文阅读笔记《Variational Prototyping-Encoder: One-Shot Learning with Prototypical Images》 核心思想 本文提出一种利用变分自动编码器(VAE)生成原型图像(PrototypicalImages),并利用最近邻算法解决小样本的图标或标志分类问题的算法。整个算法思想... 本文利用VAE结构生成原型图像,并利用编码器作为特征提取器,通过比较...
Multi-task pretraining self-supervised learning can enhance text representation. • A novel prototype-aware attention model is proposed. • Unsupervised contrastive regularization is introduced to prevent overfitting. • The proposed method achieves the best performance on four public datasets. ...
In this paper, we propose an end-to-end source-free domain adaptation semantic segmentation method via Importance-Aware and Prototype-Contrast (IAPC) learning. The proposed IAPC framework effectively extracts domain-invariant knowledge from the well-trained source model and learns domain-specific ...
Alex Mercer, also known by his Blackwatch codename Zeus, is the protagonist of Prototype and the main antagonist of Prototype 2. He was the former head researcher of the Blacklight Project at Gentek. After learning that those affiliated with the project
Be aware that in a multithreaded program, different threads could try to instantiate a class simultaneously. For this reason, a Singleton implementation that relies on an if statement to check whether the instance is null will not be thread-safe. Do not use code like that! To do this, we ...
