📄 中文摘要
谱聚类是一种基于图论的聚类方法，通过利用数据点之间的相似性来识别复杂的聚类结构。与传统的K-means算法相比，谱聚类在处理非凸形状和不同密度的聚类时表现更为优越。其核心在于构建相似度矩阵，并通过计算特征向量来获取数据的低维表示，从而有效地揭示数据的内在结构。谱聚类能够捕捉到数据中的全局信息，使其在许多实际应用中，如图像分割和社交网络分析，展现出更强的适应性和准确性。

📄 English Summary
Spectral Clustering Explained: How Eigenvectors Reveal Complex Cluster Structures
Spectral clustering is a graph-based clustering method that identifies complex cluster structures by leveraging the similarities between data points. It outperforms traditional K-means algorithms, especially when dealing with non-convex shapes and varying densities of clusters. The method constructs a similarity matrix and computes eigenvectors to obtain a low-dimensional representation of the data, effectively revealing its intrinsic structure. By capturing global information within the data, spectral clustering demonstrates enhanced adaptability and accuracy in various practical applications, such as image segmentation and social network analysis.
