Learning Concept-Based Causal Transition and Symbolic Reasoning for Visual Planning

no code implementations5 Oct 2023 Yilue Qian, Peiyu Yu, Ying Nian Wu, Yao Su, Wei Wang, Lifeng Fan

In this paper, we propose an interpretable and generalizable visual planning framework consisting of i) a novel Substitution-based Concept Learner (SCL) that abstracts visual inputs into disentangled concept representations, ii) symbol abstraction and reasoning that performs task planning via the self-learned symbols, and iii) a Visual Causal Transition model (ViCT) that grounds visual causal transitions to semantically similar real-world actions.

Latent Diffusion Energy-Based Model for Interpretable Text Modeling

2 code implementations13 Jun 2022 Peiyu Yu, Sirui Xie, Xiaojian Ma, Baoxiong Jia, Bo Pang, Ruiqi Gao, Yixin Zhu, Song-Chun Zhu, Ying Nian Wu

Latent space Energy-Based Models (EBMs), also known as energy-based priors, have drawn growing interests in generative modeling.

Unsupervised Foreground Extraction via Deep Region Competition

2 code implementations NeurIPS 2021 Peiyu Yu, Sirui Xie, Xiaojian Ma, Yixin Zhu, Ying Nian Wu, Song-Chun Zhu

Foreground extraction can be viewed as a special case of generic image segmentation that focuses on identifying and disentangling objects from the background.
