GraphPNAS: Learning Distribution of Good Neural Architectures via Deep Graph Generative Models

no code implementations28 Nov 2022 Muchen Li, Jeffrey Yunfan Liu, Leonid Sigal, Renjie Liao

Moreover, our graph generator leads to a learnable probabilistic search method that is more flexible and efficient than the commonly used RNN generator and random search methods.

Referring Transformer: A One-step Approach to Multi-task Visual Grounding

1 code implementation NeurIPS 2021 Muchen Li, Leonid Sigal

As an important step towards visual reasoning, visual grounding (e. g., phrase localization, referring expression comprehension/segmentation) has been widely explored Previous approaches to referring expression comprehension (REC) or segmentation (RES) either suffer from limited performance, due to a two-stage setup, or require the designing of complex task-specific one-stage architectures.

TDAF: Top-Down Attention Framework for Vision Tasks

no code implementations14 Dec 2020 Bo Pang, Yizhuo Li, Jiefeng Li, Muchen Li, Hanwen Cao, Cewu Lu

Such spatial and attention features are nested deeply, therefore, the proposed framework works in a mixed top-down and bottom-up manner.
