4.4 Ablation Studies

  1. Does a larger cache always improve StreamingLLM’s perplexity?
    No: increasing the cache size didn’t consistently lower perplexity, suggesting the models don’t fully use the context they get. StreamingLLM also doesn’t extend the context window: tokens evicted from the cache are forgotten.
