ReState: Noise-Level-Aware State Correction for Training-Free Object Removal in Few-Step Diffusion Models

Donghwan Lee, Sanghyun Jo, Sihyun Kim +2

Training-free object removal commonly redirects self-attention away from the target region, but on few-step distilled diffusion models this often leaves object-shaped residuals. We…

Value-Informed Schedule Trimming for Accelerated Sequential Monte Carlo Guidance in Discrete Diffusion

Jaehyeon Kim, Ziseok Lee, Siyoung Choi +1

Reward-guided discrete diffusion enables test-time alignment with downstream objectives, but applying Sequential Monte Carlo (SMC) guidance at every denoising step is computational…

Risk-Calibrated Proposal Transport for Finite-Particle Diffusion Steering

Ziseok Lee, Jaehyeon Kim, Seungwon Kim +6

Inference-time steering combines pretrained diffusion experts or rewards without retraining by changing the dynamics that transport noise to data. Feynman-Kac correction compensate…

SurfSpec: Enhancing Off-Target-Agnostic Specificity by Bounding Pocket-Ligand Geometric Mismatch

Minyeong Hwang, Yoorim Gang, Ziseok Lee +5

Lead optimization in structure-based drug design aims to improve target binding while avoiding unintended interactions with off-target pockets. However, existing affinity-driven me…

PatchGate: Narrowing the Verbalization Gap with Intrinsic Object Inventories in Frozen Vision-Language Models

Jihyung Ko, Eunji Jung, Hyeongsub Kim +4

Reliable image captioning in Vision-Language Models (VLMs) requires captions to be both precise and complete, avoiding unsupported object mentions while covering visible objects. E…

On the Collapse of Generative Paths: A Criterion and Correction for Diffusion Steering

Ziseok Lee, Minyeong Hwang, Wooyeol Lee +6

Inference-time steering adapts pretrained diffusion and flow models to new tasks without retraining, often utilizing ratio-of-densities constructions that reweight time-indexed mar…

ISAC: Training-Free Instance-to-Semantic Attention Control for Multi-Instance Generation

Sanghyun Jo, Wooyeol Lee, Ziseok Lee +3

Recent open-weight text-to-image (T2I) diffusion models still struggle with multi-instance prompts, often omitting or merging instances and mixing semantics among similar objects.…

Early Timestep Zero-Shot Candidate Selection for Instruction-Guided Image Editing

Joowon Kim, Ziseok Lee, Donghyeon Cho +4

Despite recent advances in diffusion models, achieving reliable image generation and editing remains challenging due to the inherent diversity induced by stochastic noise in the sa…

TRACE: Your Diffusion Model is Secretly an Instance Edge Detector

Sanghyun Jo, Ziseok Lee, Wooyeol Lee +3

High-quality instance and panoptic segmentation has traditionally relied on dense instance-level annotations such as masks, boxes, or points, which are costly, inconsistent, and di…

HybridLinker: Topology-Guided Posterior Sampling for Enhanced Diversity and Validity in 3D Molecular Linker Generation

Minyeong Hwang, Ziseok Lee, Kwang-Soo Kim +2

Linker generation is critical in drug discovery applications such as lead optimization and PROTAC design, where molecular fragments are assembled into diverse drug candidates via m…
