Runtime of Fast Higashi - ma-compbio/Higashi GitHub Wiki

Unless stated, all numbers reported at running Fast-Higashi at 500kb resolution on all autosomal chromosomes. All numbers are consistent with the uploaded tutorial notebook.

Runtime for tensor decomposition

main factor that decides are hyperparameters:

  1. do linear convolution or partial random walk with restart or not
  2. tolerance. (Suggested 3e-4 for high-cov data with medium number of cells, 2e-5 for low-cov data or data with large number of cells. Overall, one should try to run with 3e-4 first, inspect the results, and fine tune the model with 2e-5 or even smaller threshold when needed. Fast-Higashi will resume previous training. )
