Shivam Agarwal

I am a graduate student at University of Illinois at Urbana-Champaign (UIUC) where I study CS and AI. I am also a research assitant in Prof. Jiawei Han's Data Mining Research Group (DMG) at UIUC. Previously, I was an Engineer at Cisco and a researcher at IIIT-Delhi and Vanderbilt University. I obtained my bachelors degree in ECE from Manipal Institute of Technology, India where I graduated at the top of my class.

I am especially passionate about machine learning, natural language processing, and graph-based deep learning. I have been fortunate to contribute to a wide range of research directions, including text mining, information extraction, text representation learning, spatio-temporal information processing, reinforcement learning, quantitative finance, and computational social sciences. I would be happy to discuss any project idea at the intersection of the above areas; feel free to reach out if you are interested!

Research

I'm interested in natural machine learning, and natural language processing. I have presented my work in these areas in several top tier conferences including ACL, EMNLP, AISTATS, UAI, WWW, IJCAI, AAAI, ICDM, COLING and many more. Recently, I am working on developing self-supervised, unsupervised and weakly-supervised (i.e., leveraging minimal human supervision) text mining techniques for organizing and exploring text data.
