Yo'City: Personalized and Boundless 3D Realistic City Scene Generation via Self-Critic Expansion

CVPR 2026

Realistic 3D city generation is fundamental to a wide range of applications, including virtual reality and digital twins. However, most existing methods rely on training a single diffusion model, which limits their ability to generate personalized and boundless city-scale scenes. In this paper, we p

MMGDreamer: Mixed-Modality Graph for Geometry-Controllable 3D Indoor Scene Generation

AAAI 2025technical

Controllable 3D scene generation has extensive applications in virtual reality and interior design, where the generated scenes should exhibit high levels of realism and controllability in terms of geometry. Scene graphs provide a suitable data representation that facilitates these applications. Howe…

Adversarial Distillation Based on Slack Matching and Attribution Region Alignment

CVPR 2024poster

Adversarial distillation (AD) is a highly effective method for enhancing the robustness of small models. Contrary to expectations a high-performing teacher model does not always result in a more robust student model. This is due to two main reasons. First when there are significant differences in pr…

AGAIN: Adversarial Training With Attribution Span Enlargement and Hybrid Feature Fusion

CVPR 2023poster

The deep neural networks (DNNs) trained by adversarial training (AT) usually suffered from significant robust generalization gap, i.e., DNNs achieve high training robustness but low test robustness. In this paper, we propose a generic method to boost the robust generalization of AT methods from the…

Fast and Fine-grained Autoscaler for Streaming Jobs with Reinforcement Learning

IJCAI 2022poster

On computing clusters, the autoscaler is responsible for allocating resources for jobs or fine-grained tasks to ensure their Quality of Service. Due to a more precise resource management, fine-grained autoscaling can generally achieve better performance. However, the fine-grained autoscaling for str…

Speech-Language Pre-Training for End-to-End Spoken Language Understanding

ICASSP 2021accepted

End-to-end (E2E) spoken language understanding (SLU) can infer semantics directly from speech signal without cascading an automatic speech recognizer (ASR) with a natural language understanding (NLU) module. However, paired utterance recordings and corresponding semantics may not always be available…
