Towards Robust Sequential Decomposition for Complex Image Editing

CVPR 2026

Recent advances in visual generative models have enabled high-fidelity image editing guided by human instructions. However, these models often struggle with complex instructions involving combinatorial editing operations or inter-step dependencies. This difficulty stems from the limitations of two c

NightLab: A Dual-Level Architecture With Hardness Detection for Segmentation at Night

CVPR 2022poster

The semantic segmentation of nighttime scenes is a challenging problem that is key to impactful applications like self-driving cars. Yet, it has received little attention compared to its daytime counterpart. In this paper, we propose NightLab, a novel nighttime segmentation framework that leverages…

AutoSpace: Neural Architecture Search With Less Human Interference

ICCV 2021poster

Current neural architecture search (NAS) algorithms still require expert knowledge and effort to design a search space for network construction. In this paper, we consider automating the search space design to minimize human interference, which however faces two challenges: the explosive complexity…

HR-NAS: Searching Efficient High-Resolution Neural Architectures With Lightweight Transformers

CVPR 2021poster

High-resolution representations (HR) are essential for dense prediction tasks such as segmentation, detection, and pose estimation. Learning HR representations is typically ignored in previous Neural Architecture Search (NAS) methods that focus on image classification. This work proposes a novel NAS…

AtomNAS: Fine-Grained End-to-End Neural Architecture Search

ICLR 2020poster

Search space design is very critical to neural architecture search (NAS) algorithms. We propose a fine-grained search space comprised of atomic blocks, a minimal search unit that is much smaller than the ones used in recent NAS algorithms. This search space allows a mix of operations by composing di…

Neural Architecture Search for Lightweight Non-Local Networks

CVPR 2020poster

Non-Local (NL) blocks have been widely studied in various vision tasks. However, it has been rarely explored to embed the NL blocks in mobile neural networks, mainly due to the following challenges: 1) NL blocks generally have heavy computation cost which makes it difficult to be applied in applicat…

Guided Feature Transformation (GFT): A Neural Language Grounding Module for Embodied Agents

CoRL 2018

Recently there has been a rising interest in training agents, embodied in virtual environments, to perform language-directed tasks by deep reinforcement learning. In this paper, we propose a simple but effective neural language grounding module for embodied agents that can be trained end to end from
