Subequivariant Reinforcement Learning in 3D Multi-Entity Physical Environments

ICML 2024poster

Learning policies for multi-entity systems in 3D environments is far more complicated against single-entity scenarios, due to the exponential expansion of the global state space as the number of entities increases. One potential solution of alleviating the exponential complexity is dividing the glob…

Subequivariant Graph Reinforcement Learning in 3D Environments

ICML 2023oral

Learning a shared policy that guides the locomotion of different agents is of core interest in Reinforcement Learning (RL), which leads to the study of morphology-agnostic RL. However, existing benchmarks are highly restrictive in the choice of starting point and target point, constraining the movem…

Knowledge Representation Learning with Contrastive Completion Coding

EMNLP 2021finding

Knowledge representation learning (KRL) has been used in plenty of knowledge-driven tasks. Despite fruitfully progress, existing methods still suffer from the immaturity on tackling potentially-imperfect knowledge graphs and highly-imbalanced positive-negative instances during training, both of whic…

Reusing Discriminators for Encoding: Towards Unsupervised Image-to-Image Translation

CVPR 2020poster

Unsupervised image-to-image translation is a central task in computer vision. Current translation frameworks will abandon the discriminator once the training process is completed. This paper contends a novel role of the discriminator by reusing it for encoding the images of the target domain. The pr…
