• AA-SVD enables rapid compression of billion-parameter models without retrainingmethod 95%
  Evidencepartial

  We introduce a fast low-rank factorization-based framework for compressing large language models that enables rapid compression of billion-parameter models without retraining.

• AA-SVD accounts for both original inputs and shifted inputs from upstream compression, unlike existing factorization approachesmethod 90%
  Evidencepartial

  Unlike existing factorization-based approaches that optimize only on the original inputs... or those that rely only on shifted inputs... our approach accounts for both.

• AA-SVD refines each transformer block end-to-end to minimize block-level output distortionmethod 90%
  Evidencepartial

  Beyond individual layer compression, we further refine each transformer block end-to-end, minimizing block-level output distortion and allowing compressed layers to jointly compensate for accumulated errors.

• AA-SVD maintains functional equivalence with the original model through anchored compressiontechnical 80%
  Evidencepartial

  By anchoring each compressed layer to the original outputs while explicitly modeling input distribution shifts, our method finds a low-rank approximation that maintains functional equivalence with the original model.

  Implicationpartial

  Directly stated in abstract but requires some interpretation of 'functional equivalence'
