Lowest suggested value for lambda? #279

Hi,

Is there a minimum value that you suggest for lambda? I tested from 5 down to 0.001 using RunOptimizeALS from SeuratWrappers and it didn't seem to affect the integration much.

Best wishes, Lucy

Hi Lucy,

In most cases, lambda doesn't have a significant impact on RunOptimizeALS. Normally we set lambda = 5 by default in analyses. When it comes to online iNMF, it can have a larger effect at times.

Best,
