When I separated two linked rings with spectral clustering, k-means failed with an ARI of 0.08

Two rings linked like a chain. If a human looks at this 3D data, they will answer "two rings" in 0.1 seconds. So, can a clustering algorithm figure that out?The tricky part about this data is that the ...

Python-100-Days 机器学习实战：K-Means 聚类算法从原理到 scikit-learn 实现

聚类（Clustering）是数据挖掘与机器学习中的一类核心无监督学习技术，它不依赖任何标签，仅依据样本间的相似度或距离把数据划分为若干"簇"。本文以 Python-100-Days 项目 Day81-90/86.K-Means聚类算法 ...
