Hi! I am a final-year Ph.D. student at the Computer Science Department of UIUC, under the supervision of Prof. Jiawei Han. I am broadly interested in data mining and machine learning. My current research focuses on mining actionable knowledge from massive social sensing data and empowering intelligent applications. It falls in the intersection of social media analysis, spatiotemporal data mining, text mining, graph mining, and urban computing.
- [2018.02] One article on deep learning for IoT (Internet-of-Things) accepted by IEEE Computer.
- [2017.12] One research paper accepted by WWW 2018. We propose an attentional recurrent neural network, which achieves sota performance for next location prediction. Code and data will be released soon.
- [2017.12] One research paper accepted by ICDE 2018. We propose a method that accurately predicts the satisfactory levels for users of ride-sharing services like Uber and Didi.
- [2017.11] Two research papers accepted by AAAI 2018, one is about mobility modeling with semantic trajectories, and the other is about spatiotemporal activity modeling under data scarcity. Code and data will be released soon.
- [2017.11] Invited as an Illinois Innovator to talk about our event detection method on Illinois Podcast. Available on SoundCloud and iTunes.
- [2017.10] One full paper on reliable deep learning for sensor data accepted by UbiComp 2018.
- [2017.10] Check out the report from IT Business about our work on local event detection from social media streams.
