Crowding Prediction of In-Situ Metro Passengers Using Smart Card Data
Xiancai Tian, Chen Zhang, Baihua Zheng
The metro system is playing an increasingly important role in the urban public transit network, transferring a massive human flow across space everyday in the city. In recent years…
Probabilistic Value Selection for Space Efficient Model
Gunarto Sindoro Njoo, Baihua Zheng, Kuo-Wei Hsu +1
An alternative to current mainstream preprocessing methods is proposed: Value Selection (VS). Unlike the existing methods such as feature selection that removes features and instan…
TRIPDECODER: Study Travel Time Attributes and Route Preferences of Metro Systems from Smart Card Data
Xiancai Tian, Baihua Zheng, Yazhe Wang +2
In this paper, we target at recovering the exact routes taken by commuters inside a metro system that arenot captured by an Automated Fare Collection (AFC) system and hence remain…
KGClean: An Embedding Powered Knowledge Graph Cleaning Framework
Congcong Ge, Yunjun Gao, Honghui Weng +3
The quality assurance of the knowledge graph is a prerequisite for various knowledge-driven applications. We propose KGClean, a novel cleaning framework powered by knowledge graph…
CrowdTSC: Crowd-based Neural Networks for Text Sentiment Classification
Keyu Yang, Yunjun Gao, Lei Liang +3
Sentiment classification is a fundamental task in content analysis. Although deep learning has demonstrated promising performance in text classification compared with shallow model…
Bus Frequency Optimization: When Waiting Time Matters in User Satisfaction
Songsong Mo, Zhifeng Bao, Baihua Zheng +1
Reorganizing bus frequency to cater for the actual travel demand can save the cost of the public transport system significantly. Many, if not all, existing studies formulate this a…
DeepDualMapper: A Gated Fusion Network for Automatic Map Extraction using Aerial Images and Trajectories
Hao Wu, Hanyuan Zhang, Xinyu Zhang +3
Automatic map extraction is of great importance to urban computing and location-based services. Aerial image and GPS trajectory data refer to two different data sources that could…
