WebbThe cluster centers are each 1xloci that meet the requirements. Each cell may have only a subset of these loci. There is no latent space. mtx header line 3 is loci cells total_entries. Then each line is locus cell value; I normalize the log likelihoods for each cell to each cluster to sum to 1 and then do a PCA (or other dim reduction) on that. WebbIn the regular lattice setting, a cluster is a maximum set of occupied sites which are pairwise joined by paths on the lattice only traversing occupied sites. In general, a cluster is component of the graph. The size s of a cluster is the number of nodes in the component. Note that infinite graphs allow for infinite cluster sizes.
