Demonstration-guided Deep Reinforcement Learning for Coordinated Ramp Metering and Perimeter Control in Large Scale Networks

no code implementations4 Mar 2023 Zijian Hu, Wei Ma

This study considers two representative control approaches: ramp metering for freeways and perimeter control for homogeneous urban roads, and we aim to develop a deep reinforcement learning (DRL)-based coordinated control framework for large-scale networks.

Heterogeneous Line Graph Transformer for Math Word Problems

no code implementations11 Aug 2022 Zijian Hu, Meng Jiang

We originally planned to employ existing models but realized that they processed a math word problem as a sequence or a homogeneous graph of tokens.

SimMER: Simple Maximization of Entropy and Rank for Self-supervised Representation Learning

no code implementations29 Sep 2021 Zhengyu Yang, Zijian Hu, Xuefeng Hu, Ram Nevatia

With both entropy and rank maximization, our method surpasses the state-of-the-art on CIFAR-10 and Mini-ImageNet under the standard linear evaluation protocol.

SimPLE: Similar Pseudo Label Exploitation for Semi-Supervised Classification

1 code implementation CVPR 2021 Zijian Hu, Zhengyu Yang, Xuefeng Hu, Ram Nevatia

Combining the Pair Loss with the techniques developed by the MixMatch family, our proposed SimPLE algorithm shows significant performance gains over previous algorithms on CIFAR-100 and Mini-ImageNet, and is on par with the state-of-the-art methods on CIFAR-10 and SVHN.
