海外TECH	DEV Community	Spectral Clustering Algorithm Demystified	https://dev.to/rajaniraiyn/spectral-clustering-algorithm-demystified-d8i	Spectral Clustering Algorithm DemystifiedSpectral clustering is a method of clustering data points based on their similarity or affinity rather than their distance or compactness The algorithm uses the eigenvalues and eigenvectors of a similarity matrix to project the data into a lower dimensional space where the clusters become more separable The algorithm can handle clusters of arbitrary shapes and sizes unlike k means which assumes spherical clusters WorkingStep Construct a similarity matrix S for the data points where S i j represents the similarity or affinity between the i th and j th data point The similarity can be measured by various methods such as Gaussian kernel k nearest neighbors or epsilon neighborhood Step Compute the degree matrix D for the similarity matrix S where D i i is the sum of the i th row of S and D i j is zero for i not equal to j The degree matrix represents the degree of connectivity of each data point Step Compute the Laplacian matrix L for the similarity matrix S and the degree matrix D where L D S The Laplacian matrix captures the difference between the degree of a data point and its similarity to other data points Step Compute the eigenvalues and eigenvectors of the Laplacian matrix L and sort them in ascending order Choose the k smallest eigenvalues and their corresponding eigenvectors where k is the number of clusters desired The eigenvectors represent the new features that best capture the structure of the data Step Form a matrix U by stacking the k eigenvectors as columns Each row of U represents a data point in the new feature space Step Apply k means clustering on the rows of U to obtain k clusters Pseudocode Input data points X number of clusters k similarity measure S Output cluster assignments C Step Construct the similarity matrix SS similarity matrix X S Step Compute the degree matrix DD degree matrix S Step Compute the Laplacian matrix LL laplacian matrix D S Step Compute the eigenvalues and eigenvectors of LE V eigen L Sort the eigenvalues and eigenvectors in ascending orderE V sort E V Choose the k smallest eigenvalues and eigenvectorsE k E k V k V k Step Form the matrix U by stacking V k as columnsU stack V k Step Apply k means clustering on UC kmeans U k Return the cluster assignmentsreturn C AdvantagesIt can handle clusters with complex shapes and sizes unlike k means which assumes spherical clusters It can capture the global structure of the data by using the spectral properties of the similarity matrix It can be easily implemented by using standard linear algebra methods DisadvantagesIt requires choosing k in advance which can be difficult or arbitrary It is sensitive to the choice of similarity measure which can affect the quality and number of clusters It can be computationally expensive as it requires calculating and decomposing a large similarity matrix References and Further ReadingSpectral Clustering in Machine Learning GeeksforGeeksA Tutorial on Spectral Clustering arXiv orgSpectral Clustering GitHub PagesThis will be a multipart series which will follow up with more clustering algorithms with their working pseudocode advantages and disadvantages Please stay tuned for more such content If you liked this post please share it with your friends and fellow developers And don t forget to follow us for more programming tutorials and examples And also have a look my Portfoliocode‍together Githubconnect LinkedIn	2023-06-20 18:30:00
