@andreyanufr Fixed, added test for that. Please take a look: |

The word perplexity for per-channel NF4 quantization with Scale Estimation is reproduced with the latest changes in PR and comparable with what I got with the same changes before merge with develop: 10.8850 vs 10.8830 |

Changes
Supported NF4 mode for Scale Estimation and AWQ.
All results below were collected w/ and w/o Scale estimation algorithms and w/ Lora Correction algorithm.
Reason for changes
NF4 per-channel with scale estimation may give promising results for NPU, since the accuracy is on par with int4 group-wise quantization.
