Clustering is a versatile technique designed to group data points based on their intrinsic similarities. Imagine sorting a collection of various fruits into separate baskets based on their types. In machine learning, clustering is an unsupervised learning method, diligently working to uncover hidden patt...
Document classication is a signicant application of supervised learning which requires a labeled dataset for training the classier. However, research publication records available on Google Scholar and dblp services are not labeled. First, manual annotation of a large body of scientic research work ...
最近self-supervised learning很火,方法上简单明了,但确实work的很好,尤其是用在clustering或是所谓self-labelling(不需要人工标注,而可以获得label assignment) 任务。本文中,我尝试根据自己的理解,对3篇近期self-supervised representation learning和clustering结合的方法进行如下总结,具体实验部分请参考原文,其中2篇是来自...
Self-supervised Learning.A popular form of unsupervised learning, called “self-supervised learning” [52], uses pretext tasks to replace the labels annotated by humans by “pseudo-labels” directly computed from the raw input data. For example, Doerschet al. [13] use the prediction of the re...
In this section we will describe the K-means and expectation maximization (EM) belonging to the class of unsupervised learning algorithms, as well as the K-NN algorithm, belonging to the class of supervised learning algorithms. 14.1.4.1 K-Means Clustering In the K-means clustering algorithm, ...
We must presume, as in the case of supervised learning, that all patterns are defined in terms of features that form one-dimensional feature vectors. The basic steps to be taken by an expert to establish a clustering function are as follows: • Feature selection: Features should be chosen ...

作者的回复也很道理嘛:supervised learning不需要用到clustering啊,比如train一个模型去预测图片的patch啊,旋转角度啊,等等。那将representation learning和clustering同时学习的,不就是Facebook那篇DeepCluster[1]嘛: 图1,图片来源于DeepCluster:https://arxiv.org/pdf/1807.05520.pdf 既然已经有人做了simultaneous ...
We release paper and code for SwAV, our new self-supervised method. SwAV pushes self-supervised learning to only 1.2% away from supervised learning on ImageNet with a ResNet-50! It combines online clustering with a multi-crop data augmentation....
self-supervised learning的一个最重要的目标就是在不利用标签的情况下学到robust的表征。近期一系列的工作包括:CPC,AMDIM,BYOL,SimCLR,MOCO,BYOL等,通过将contrastive loss和image transformation结合起来来实现这一目标。contrastive loss通过比较成对图片的表征,将同一张图片的不同transformation的表征拉近,将不同图片的...
