> We need to add a unit test to {{LDASuite}} which check that empty documents are handled
appropriately without crashing. This would require defining an empty corpus within {{LDASuite}}
and adding tests for the available LDA optimizers (currently EM and Online). Note that only
{{SparseVector}}s can be empty.
