KSimplex Geometric Attention Prior

Geometric cross-attention prior for SD1.5 using pentachoron (4-simplex) structures.

Architecture

Component	Params
SD1.5 UNet (frozen)	859,520,964
Geo prior (trained)	4,845,725

The geometric prior modulates CLIP encoder hidden states through 4-layer stacked k-simplex attention before they reach the 16 cross-attention blocks in the UNet.

Simplex Configuration

Parameter	Value
k (simplex dim)	4
Embedding dim	32
Feature dim	768
Stacked layers	4
Attention heads	8
Base deformation	0.25
Residual blend	learnable
Timestep conditioned	True

Usage

python

from sd15_trainer_geo.pipeline import load_pipeline, load_geo_from_hub

# Load base SD1.5 + fresh geo prior
pipe = load_pipeline()

# Load trained geo weights from this repo
load_geo_from_hub(pipe, "AbstractPhil/sd15-rectified-geometric-matching")

# Or one-shot: load base + geo in one call
pipe = load_pipeline(geo_repo_id="AbstractPhil/sd15-rectified-geometric-matching")
