它实现了一个积极的循环,其中更好的自信对导致更好的表示,更好的表示将识别更好的自信对。 Selective-Supervised Contrastive Learning 我们从固定符号开始。标量是用小写字母写的。向量用小写黑体字母表示。让[A]作为事件A的指示器。[z] = {1,……,z},考虑一个分类任务,有C类。我们给出了一个噪声标记的数据...

对比学习目前主要分为实例对比学习(instance-wise contrastive learning)和原型对比学习(prototypical contrastive learning)。实例对比学习是站在实例层次上的,推开负样本的距离,以获得不同图像之间的合理的局部结构;原型对比学习是站在聚类后的类层次上的,获得聚集在相应的集群中心周围的紧凑的图像表示,从而捕获一些可以由...
Less is More: Selective reduction of CT data for self-supervised pre-training of deep learning models with contrastive learning improves downstream classification performance - Wolfda95/Less_is_More
This repository provides a PyTorch implementation and model weights for HCSC (HierarchicalContrastiveSelectiveCoding), whose details are inthis paper(accepted by CVPR 2022). HCSC is an effective and efficient method to pre-train image encoders in aself-supervisedfashion. In general, this method seeks...
Parameters of each network (except the randomly initialized untrained Resnet-50 model) were first optimized for object categorization performance using supervised learning methods15. At the end of this training, all the parameters were fixed and the internal activations at the individual layers of the...

supervised learning signals, negative pseudo-labels are created for unlabeled data with low prediction confidence. These positive and negative pseudo-labeled data points, combined with a small set of labeled samples, are subsequently trained to optimize the performance of semi-supervised learning. Please...
Enabling On-Device Self-Supervised Contrastive Learning With Selective Data ContrastDewen ZengJingtong HuYawen WuYiyu ShiZhepeng Wang
In this paper, to solve this problem, we propose a new Supervised Relational Learning (SuperRL) model with selective neighbor entities for few-shot KG completion. In SuperRL, we first enhance head and tail entity embeddings based on a cascaded embedding enhancement network with different neighbor...
