| # BFS (Best Face Swap) — Optimized & De-blurred LoRA Variants
|
|
|
| This repository contains cleaned and optimized variations of the [Alissonerdx/BFS-Best-Face-Swap](https://huggingface.co/Alissonerdx/BFS-Best-Face-Swap) LoRA.
|
|
|
| ### Motivation & Problem
|
| While the original BFS LoRA provides solid face swap transfer, it often introduces significant **blurriness, fine texture loss, and a plastic/soapy degradation** across skin areas.
|
|
|
| To resolve this issue while retaining identity likeness, these variants were optimized using weight pruning and stochastic drop masking:
|
| - **Pruning (20%)**: Removes the bottom 20% weakest/noisy weight layers that cause unwanted model drift and texture degradation.
|
| - **DARE Drop Masking (without Rescaling)**: Random drop-masking (density 0.50–0.60) applied **without** magnitude rescaling. Skipping the rescaling step prevents artificial weight amplification, successfully stripping away soapy blur while keeping the facial structure intact.

| ### Available Variants
|
|
|
| | File | Pruning & Masking | Description |
|
| | :--- | :--- | :--- |
|
| | `bfs_dare60-avgrank30.safetensors` | Drop Mask (density 0.60, no rescale), avg rank 30 | Gentle cleanup; preserves strong likeness while noticeably reducing original blur. |
|
| | `bfs_prune20_dare50-avgrank26.safetensors` | 20% Pruned + Drop Mask (density 0.50, no rescale), avg rank 26 | Strongest de-blurring and detail retention; best for crisp skin textures and sharp eyes. |
|
| | `bfs_prune20_dare60-avgrank30.safetensors` | 20% Pruned + Drop Mask (density 0.60, no rescale), avg rank 30 | Balanced profile: removes muddy blur while keeping likeness very close to the original. |
