I am looking for technically strong and ambitious PhD students interested in applications of artificial intelligence (machine learning, natural language processing, crowdsourcing, automated planning). Please contact me if you are one of them. I am also interested in industry related problems that can be solved using AI techniques. Contact me if you think you have an interesting problem.

I am not looking for winter/summer interns or students for short-term (less than a year) projects. Please do not contact me with such requests.

Research
My main research interests are in the field of Artificial Intelligence. At present I am working on the following projects:
  • Open Information Extraction: We hope to overcome the "knowledge-acquisition bottleneck" by automatically extracting information from natural language text in a domain-independent manner. We work on improving the quality of Open IE extractors by pushing their precision and recall. Our recentmost Open IE extractor is publically available. We are currently extending it to process noun phrases and numeric extractions better. A recent paper on this work.

  • AI Applications to Crowd-sourcing: Crowd-sourcing has taken over the business world by storm in the last few years. Although it is touted as "Artificial Artificial Intelligence", there are huge opportunities for AI to contribute to its success. A vision paper describes our approach to this synergy. We have investigated decision-theoretic techniques to automatically control workflows on a crowd-sourcing platform such as Amazon's Mechanical Turk, and have obtained significant quality improvements for the same price. Recent papers on this work: Paper 1, Paper 2, and Paper 3.

  • Abstractions in Machine Learning: We hope to exploit symmetries and other implicit domain abstractions to scale up a variety of machine learning and inference algorithms. We work on reducing computation in Markov Decision Process (MDP) algorithms such as UCT by aggregating symmetric states and state-action pairs. We also work on exploiting similar properties in the context of probabilistic inference. A recent paper on this work.

  • Coherent Large-Scale Multi-Document Summarization: How to produce coherent, human readable summaries from a set of 10 related documents? How about 100? How about 1000? What is best summary format when the amount of information that is summarized is huge? We answer these difficult questions through two systems, GFLOW and SUMMA. The first is coherent summarizer for short document collections and the latter produces hierarchical summaries for large collections. Recent papers on this work: Paper 1 and Paper 2. And demos: Demo 1 and Demo 2.

  • Applications of Open IE: Open Information Extraction is a domain-independent knowledge representation language that is different from linguistic suggestions such as semantic role labeling or domain-specific ontologies. We work on exploring the various applications that Open IE enables. We recently released OREO, a rapidly retargetable software to map open extractions to a domain ontology. In this recent paper we show that Open IE representation beats dependency parsing, and semantic role labelers in learning useful word vector representations via deep learning. Earlier, in this paper we used Open IE to automatically induce domain-independent event schemas.


Hobbies
In my personal time, I can be found listening to, playing, or singing hindustani classical music. I performed with a Seattle light Indian music band called Pratidhwani (our last show was Kashish in December 2012). I was also involved with Seattle's local cricket tournament where I tried my fingers at off-spinning. Movies and cooking take up whatever remaining free time I have.

Here is a website I host that contains interesting links about hindustani classical music.
