The Token Is a Group Element: On Lie-Algebra Attention over Matrix Lie Groups
Przemyslaw Musialski
We place the attention token on the group: a token is an element of a matrix Lie group -- a bare transformation, with no feature payload and no external action ca…
StippleDiffusion: Capacity-Constrained Stippling using Controlled Diffusion
Ofir Gilad, Aleksander Plocharski, Przemyslaw Musialski +1
Stipple patterns, point sets whose local density tracks a target image, are traditionally produced by per-density iterative optimizers, which are slow, non-differentiable, and must…
Pro-DG: Procedural Diffusion Guidance for Architectural Facade Generation
Aleksander Plocharski, Jan Swidzinski, Przemyslaw Musialski
We use hierarchical procedural rules for the generation of control maps within the stable diffusion framework to produce photo-realistic architectural facade images. Starting from…
STEP-Parts: Geometric Partitioning of Boundary Representations for Large-Scale CAD Processing
Shen Fan, MikoÅaj Kida, Przemyslaw Musialski
Many CAD learning pipelines discretize Boundary Representations (B-Reps) into triangle meshes, discarding analytic surface structure and topological adjacency and thereby weakening…
INST-Align: Implicit Neural Alignment for Spatial Transcriptomics via Canonical Expression Fields
Bonian Han, Cong Qi, Przemyslaw Musialski +1
Spatial transcriptomics (ST) measures mRNA expression while preserving spatial organization, but multi-slice analysis faces two coupled difficulties: large non-rigid deformations a…
Beyond Segmentation: Structurally Informed Facade Parsing from Imperfect Images
Maciej Janicki, Aleksander Plocharski, Przemyslaw Musialski
Standard object detectors typically treat architectural elements independently, often resulting in facade parsings that lack the structural coherence required for downstream proced…
