WebApr 8, 2024 · In this note, I will review a popular clustering algorithm called spectral clustering. We will discuss its connection to the min-cut problem in graph partitioning, and then look at 2 methods to extend it to multi-class clustering. This post is based heavily on this tutorial. Similarity graph and the Laplacian matrix WebAn apparatus includes a processing device configured to obtain first and second sets of data records, each data record comprising a string associated with an attribute. The processing device is also configured to generate a similarity matrix, wherein entries of the similarity matrix comprise values characterizing similarity between respective pairs of the strings …
