Hi Guys,
With the command
retriever = RagRetriever.from_pretrained("facebook/rag-token-base", index_name="compressed", use_dummy_dataset=True)
We can choose index_name either “compressed” or “exact”, what is the difference between these two ?
I also found from some topic (could not find it now), that @lhoestq suggested to use “compressed” index to match the performance of the paper; why is that the case ?
Query: @lhoestq
