Run NMF (multiple runs)

This version runs NMF on dense inputs (think bulk RNAseq experiments) across a set of random initialisations and returns the results across these runs. Assumes samples x features.

Params

• data - The data on which to run a single NMF run. Assumes samples x features.
• k - Number of k to return
• preprocessing - String. Shall additional pre-processing be applied, see parse_nmf_processing.
• nmf_hals_params - Optional HalsOpts parameters.
• n_runs - Number of runs at this k
• base_seed - The base seed.
• verbose - If 0 -> silent or 1 for normal verbosity, 2 for detailed verbosity.

Returns

StabilisedNmfResult or errors.
