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...
而使用Logistic回归,神经网络和支持向量机处理分类问题时,也是利用训练样本自身带有标记即种类,例如进行垃圾邮件分类时是利用已有的垃圾邮件(标记为1)和非垃圾邮件(标记为0),进行数字识别时,变量是每个像素点的值,而标记是数字本身的值。我们把使用带有标记的训练样本进行学习的算法称为监督学习(Supervised Learning)。...
The clustering method is a type of unsupervised learning that consists of similar characteristics within a group and different characteristics between groups through the characteristics of individuals. This means that there are no actual labels, but clustering gives each object a new label (a risk-bas...
In an example, Principal Component Analysis (PCA) [19] is a method that transforms sample attributes into a form that would have the highest variance, thus more suitable for discrimination tasks with an additional benefit of reduced dimensions. In general, this concept can directly be generalized...
Clustering is considered as the most important unsupervised learning approach. • Since dissimilarity is fundamental to the definition of a cluster, a measure of the dissimilarity between two examples drawn from the same attribute space is essential to most clustering procedures. Because of the ...
Clustering is a class of unsupervised learning methods that has been extensively applied and studied in computer vision. Little work has been done to adapt it to the end-to-end training of visual features on large-scale datasets. In this work, we present DeepCluster, a clustering method that...

In the era of single-cell sequencing, there is a growing need to extract insights from data with clustering methods. Here, we introduce Forest Fire Clustering, an efficient and interpretable method for cell-type discovery from single-cell data. Forest Fire Clustering makes minimal prior assumptions...
2017Multi-view Learning Overview:Recent Progress and New ChallengesIF 2013A Survey on Multi-view LearningArxiv Papers & Codes According to the integrity of multi-view data, the paper is divided into deep multi-view clustering methods and deep incomplete multi-view clustering approaches. ...
Because K-means clustering is an unsupervised machine learning method, labels are optional. However, if your dataset already has a label column, you can use those values to guide selection of the clusters, or you can specify that the values be ignored. ...
