What papers say

Verbatim critique sentences, each from a paper that cites ICAE as a baseline.

Methods that over-compress inputs (e.g. ICAE) risk discarding critical content.

— SARA: Selective and Adaptive Retrieval-augmented Generation with Context Compression

“While explicit methods are generally agnostic to downstream LLMs and therefore more practical, they may suffer from higher compression loss due to the over-removal of input tokens.”
