Fast Diffusion-Based Counterfactuals for Shortcut Removal and Generation

1 code implementation21 Dec 2023 Nina Weng, Paraskevas Pegios, Eike Petersen, Aasa Feragen, Siavash Bigdeli

Via a novel inpainting-based modification we spatially limit the changes made with no extra inference step, encouraging the removal of spatially constrained shortcut features while ensuring that the shortcut-free counterfactuals preserve their remaining image features to a high degree.

GramGAN: Deep 3D Texture Synthesis From 2D Exemplars

no code implementations NeurIPS 2020 Tiziano Portenier, Siavash Bigdeli, Orcun Goksel

Inspired by recent advances in natural texture synthesis, we train deep neural models to generate textures by non-linearly combining learned noise frequencies.
