Differentiable Parsing and Visual Grounding of Natural Language Instructions for Object Placement
Zirui Zhao, Wee Sun Lee, David Hsu
We present a new method, PARsing And visual GrOuNding (ParaGon), for grounding natural language in object placement tasks. Natural language generally describes objects and spatial…
None Class Ranking Loss for Document-Level Relation Extraction
Yang Zhou, Wee Sun Lee
Document-level relation extraction (RE) aims at extracting relations among entities expressed across multiple sentences, which can be viewed as a multi-label classification problem…
Graph Representation Learning with Individualization and Refinement
Mohammed Haroon Dupty, Wee Sun Lee
Graph Neural Networks (GNNs) have emerged as prominent models for representation learning on graph structured data. GNNs follow an approach of message passing analogous to 1-dimens…
Context-Hierarchy Inverse Reinforcement Learning
Wei Gao, David Hsu, Wee Sun Lee
An inverse reinforcement learning (IRL) agent learns to act intelligently by observing expert demonstrations and learning the expert's underlying reward function. Although learning…
ExPoSe: Combining State-Based Exploration with Gradient-Based Online Search
Dixant Mittal, Siddharth Aravindan, Wee Sun Lee
Online tree-based search algorithms iteratively simulate trajectories and update action-values for a set of states stored in a tree structure. It works reasonably well in practice…
