Efficient Unsupervised Environment Design through Hierarchical Policy Representation Learning
Dexun Li, Sidney Tio, Pradeep Varakantham
Unsupervised Environment Design (UED) has emerged as a promising approach to developing general-purpose agents through automated curriculum generation. Popular UED methods focus on…
EduQate: Generating Adaptive Curricula through RMABs in Education Settings
Sidney Tio, Dexun Li, Pradeep Varakantham
There has been significant interest in the development of personalized and adaptive educational tools that cater to a student's individual learning progress. A crucial aspect in de…
Enhancing the Hierarchical Environment Design via Generative Trajectory Modeling
Dexun Li, Pradeep Varakantham
Unsupervised Environment Design (UED) is a paradigm for automatically generating a curriculum of training environments, enabling agents trained in these environments to develop gen…
Diversity Induced Environment Design via Self-Play
Dexun Li, Wenjun Li, Pradeep Varakantham
Recent work on designing an appropriate distribution of environments has shown promise for training effective generally capable agents. Its success is partly because of a form of a…
Generalization through Diversity: Improving Unsupervised Environment Design
Wenjun Li, Pradeep Varakantham, Dexun Li
Agent decision making using Reinforcement Learning (RL) heavily relies on either a model or simulator of the environment (e.g., moving in an 8x8 maze with three rooms, playing Ches…
Hidden State Approximation in Recurrent Neural Networks Using Continuous Particle Filtering
Dexun Li
Using historical data to predict future events has many applications in the real world, such as stock price prediction; the robot localization. In the past decades, the Convolution…
Towards Soft Fairness in Restless Multi-Armed Bandits
Dexun Li, Pradeep Varakantham
Restless multi-armed bandits (RMAB) is a framework for allocating limited resources under uncertainty. It is an extremely useful model for monitoring beneficiaries and executing ti…
Efficient Resource Allocation with Fairness Constraints in Restless Multi-Armed Bandits
Dexun Li, Pradeep Varakantham
Restless Multi-Armed Bandits (RMAB) is an apt model to represent decision-making problems in public health interventions (e.g., tuberculosis, maternal, and child care), anti-poachi…
CLAIM: Curriculum Learning Policy for Influence Maximization in Unknown Social Networks
Dexun Li, Meghna Lowalekar, Pradeep Varakantham
Influence maximization is the problem of finding a small subset of nodes in a network that can maximize the diffusion of information. Recently, it has also found application in HIV…
