Simple Unsupervised Object-Centric Learning for Complex and Naturalistic Videos

1 code implementation27 May 2022 Gautam Singh, Yi-Fu Wu, Sungjin Ahn

Unsupervised object-centric learning aims to represent the modular, compositional, and causal structure of a scene as a set of object representations and thereby promises to resolve many critical limitations of traditional single-vector representations such as poor systematic generalization.

TransDreamer: Reinforcement Learning with Transformer World Models

no code implementations19 Feb 2022 Chang Chen, Yi-Fu Wu, Jaesik Yoon, Sungjin Ahn

We then share this world model with a transformer-based policy network and obtain stability in training a transformer-based RL agent.

SPACE: Unsupervised Object-Oriented Scene Representation via Spatial Attention and Decomposition

4 code implementations ICLR 2020 Zhixuan Lin, Yi-Fu Wu, Skand Vishwanath Peri, Weihao Sun, Gautam Singh, Fei Deng, Jindong Jiang, Sungjin Ahn

Previous approaches for unsupervised object-oriented scene representation learning are either based on spatial-attention or scene-mixture approaches and limited in scalability which is a main obstacle towards modeling real-world scenes.
