Erased but Exploitable: Black-box Embedding-Aware Prompting Against Unlearned Text-to-Image Diffusion Models

Arian Komaei Koma, Seyed Amir Kasaei, AmirMahdi Sadeghzadeh +1

Machine unlearning aims to remove specific concepts from pretrained text-to-image diffusion models, yet several white- and black-box attacks have been introduced to make the model…

Wiring the 'Why': A Unified Taxonomy and Survey of Abductive Reasoning in LLMs

Moein Salimi, Shaygan Adim, Danial Parnian +3

Regardless of its foundational role in human discovery and sense-making, abductive reasoning--the inference of the most plausible explanation for an observation--has been relativel…
