Two Calm Ends and the Wild Middle: A Geometric Picture of Memorization in Diffusion Models

ICML 2026poster

Diffusion models generate high-quality samples but can also memorize training data, raising serious privacy concerns. Understanding the mechanisms governing when memorization versus generalization occurs remains an active area of research. In particular, it is unclear where along the noise schedule …

The Devil is in the Prompts: Retrieval-Augmented Prompt Optimization for Text-to-Video Generation

CVPR 2025poster

The evolution of Text-to-video (T2V) generative models, trained on large-scale datasets, has been marked by significant progress. However, the sensitivity of T2V generative models to input prompts highlights the critical role of prompt design in influencing generative outcomes. Prior research has pr…

Towards Realistic Example-based Modeling via 3D Gaussian Stitching

CVPR 2025poster

Using parts of existing models to rebuild new models, commonly termed as example-based modeling, is a classical methodology in the realm of computer graphics. Previous works mostly focus on shape composition, making them very hard to use for realistic composition of 3D objects captured from real-wor…

A General Implicit Framework for Fast NeRF Composition and Rendering

AAAI 2024technical

A variety of Neural Radiance Fields (NeRF) methods have recently achieved remarkable success in high render speed. However, current accelerating methods are specialized and incompatible with various implicit methods, preventing real-time composition over various types of NeRF works. Because NeRF rel…

RobIR: Robust Inverse Rendering for High-Illumination Scenes

NeurIPS 2024poster

Implicit representation has opened up new possibilities for inverse rendering. However, existing implicit neural inverse rendering methods struggle to handle strongly illuminated scenes with significant shadows and slight reflections. The existence of shadows and reflections can lead to an inaccurat…

Zero-Shot Learners for Natural Language Understanding via a Unified Multiple Choice Perspective

EMNLP 2022main

We propose a new paradigm for zero-shot learners that is format agnostic, i.e., it is compatible with any format and applicable to a list of language tasks, such as text classification, commonsense reasoning, coreference resolution, and sentiment analysis. Zero-shot learning aims to train a model on…
