How do I run signatureanalyzer with a GPU?

If you are using a cloud computing service, you first need to attach a GPU to your compute instance. Following this, you need to install the necessary drivers to allow your machine to communicate with your GPU. Instructions on how to do this may be found setting_up_cuda.md

What are the default values of the algorithm hyperparameters?

You can view these either by the command-line interface (CLI) or by the function in the python API. An explanation is available in each. To view the command line arguments (& defaults):

signatureanalyzer -h

Python API:

import signatureanalyzer as sa

sa.ardnmf?

One note: each of the individual helpers for each input type, sa.run_maf, sa.run_spectra, sa.run_matrix calls sa.ardnmf. Thus the ardf-nmf kwargs are passed to sa.ardnmf with the default values specified.
