Multiclass Semi-Supervised Learning on Graphs using Ginzburg-Landau Functional Minimization
Cristina Garcia-Cardona, Arjuna Flenner, Allon G. Percus
We present a graph-based variational algorithm for classification of high-dimensional data, generalizing the binary diffuse interface model to the case of multiple classes. Motivat…
Spectral Clustering with Epidemic Diffusion
Laura M. Smith, Kristina Lerman, Cristina Garcia-Cardona +2
Spectral clustering is widely used to partition graphs into distinct modules or communities. Existing methods for spectral clustering use the eigenvalues and eigenvectors of the gr…
Multiclass Data Segmentation using Diffuse Interface Methods on Graphs
Cristina Garcia-Cardona, Ekaterina Merkurjev, Andrea L. Bertozzi +2
We present two graph-based algorithms for multiclass segmentation of high-dimensional data. The algorithms use a diffuse interface model based on the Ginzburg-Landau functional, re…
