Efficiently Learning Branching Networks for Multitask Algorithmic Reasoning
Dongyue Li, Zhenshuo Zhang, Minxuan Duan +2
The paper proposes branching neural networks that automatically partition multiple algorithmic reasoning tasks into a hierarchical tree structure, enabling efficient multitask lear…
Learning Multimodal Embeddings for Traffic Accident Prediction and Causal Estimation
Ziniu Zhang, Minxuan Duan, Haris N. Koutsopoulos +1
We consider analyzing traffic accident patterns using both road network data and satellite images aligned to road graph nodes. Previous work for predicting accident occurrences rel…
Efficient Estimation of Kernel Surrogate Models for Task Attribution
Zhenshuo Zhang, Minxuan Duan, Hongyang R. Zhang
Modern AI agents such as large language models are trained on diverse tasks -- translation, code generation, mathematical reasoning, and text prediction -- simultaneously. A key qu…
Scalable Multi-Objective and Meta Reinforcement Learning via Gradient Estimation
Zhenshuo Zhang, Minxuan Duan, Youran Ye +1
We study the problem of efficiently estimating policies that simultaneously optimize multiple objectives in reinforcement learning (RL). Given objectives (or tasks), we seek th…
