Shortcut Diffusion Training with Cumulative Consistency Loss: An Optimal Control View

ICLR 2026poster

Although iterative denoising (i.e., diffusion/flow) methods offer strong generative performance, they suffer from low generation efficiency, requiring hundreds of steps of network forward passes to simulate a single sample. Mitigating this requires taking larger step-sizes during simulation, thereby…

UniVerse: A Unified Modulation Framework for Segmentation-Free, Disentangled Multi-Concept Personalization

CVPR 2026

Personalized visual understanding has advanced significantly, yet existing approaches struggle to localize and extract specific concepts when input images contain multiple objects. Many prior methods rely heavily on segmentation-based supervision or exhibit poor compositional generalization, limitin

Boundary-Aware Uncertainty for Feature Attribution Explainers

AISTATS 2024poster

Post-hoc explanation methods have become a critical tool for understanding black-box classifiers in high-stakes applications. However, high-performing classifiers are often highly nonlinear and can exhibit complex behavior around the decision boundary, leading to brittle or misleading local explanat…

Solving Masked Jigsaw Puzzles with Diffusion Vision Transformers

CVPR 2024poster

Solving image and video jigsaw puzzles poses the challenging task of rearranging image fragments or video frames from unordered sequences to restore meaningful images and video sequences. Existing approaches often hinge on discriminative models tasked with predicting either the absolute positions of…

Inferring Relational Potentials in Interacting Systems

ICML 2023oral

Systems consisting of interacting agents are prevalent in the world, ranging from dynamical systems in physics to complex biological networks. To build systems which can interact robustly in the real world, it is thus important to be able to infer the precise interactions governing such systems. Exi…

Reliable Estimation of KL Divergence using a Discriminator in Reproducing Kernel Hilbert Space

NeurIPS 2021spotlight

Estimating Kullback–Leibler (KL) divergence from samples of two distributions is essential in many machine learning problems. Variational methods using neural network discriminator have been proposed to achieve this task in a scalable manner. However, we noticed that most of these methods using neur…
