Learning and Incentives in Systems with Humans in the Loop

Chien-Ju Ho, Cornell University
Monday, March 27 (12:05 p.m. - 1:20 p.m.)
208 IST Building

Chien-Ju will present his research which addresses the challenges in utilizing and eliciting data from humans. In particular, he will introduce the problem of actively purchasing data from humans for solving machine learning tasks, and demonstrate how to convert a large class of machine learning algorithms into pricing and learning mechanisms. He will also discuss how to obtain high-qualitydata from humans using financial incentives and present our findings in a comprehensive set of behavioral experiments conducted on Amazon Mechanical Turk.

Protecting User Security and Privacy in Emerging Platforms

Yuan Tian, Carnegie Mellon University
Tuesday, March 28 (12:05 p.m. - 1:20 p.m.)
208 IST Building

In this talk, she’ll present two of his example projects in the thrusts of (1) Identify and understand new threats, as well as (2) design and implement secure and privacy preserving systems. In the first example project, she works on defending against new privacy threats in web.

Life in High-Dimensional Space: Modeling Sequential Changes in Gene Expression

Joshua Welch, University of North Carolina at Chapel Hill
Thursday, March 30 (12:05 p.m. - 1:20 p.m.)
208 IST Building

He will present an approach that reveals key properties of a biological process by positing the process as a nonlinear manifold embedded in high-dimensional gene expression space. The approach constructs a manifold from single cell data in an unsupervised manner and uses the geometry of the manifold to order cells according to position in the process and to discover “branches” and “loops” in the process. In addition, he will show how manifold representations of biological processes can be used to integrate multiple kinds of single cell genomic measurements performed on cells undergoing a common process.

Going to school on a robot: Using telepresence robots to let homebound children go to school

Judy Olson, Donald Bren Professor Emerita, Information and Computer Sciences, University of California Irvine
Monday, April 3 (2:30 p.m. - 3:45 p.m.)
113 IST Building (Cybertorium)

Children who are homebound because of medical conditions like cancer treatments or immune deficiency are normally offered tutoring for 4-5 hours a week. This tutoring may help them keep up academically, but it does nothing for their friendships or social learning. Recently, technology has created the opportunity to bring these students to school using telepresence robots, units that pair videoconferencing with a remote controlled robot. How do these students fare? Do they feel "present" in school? How do teachers and classmates accommodate these students? The telepresence robots were designed for use by adults in offices and hospitals; what features should be changed to accommodate children going to school? What other kinds of students might benefit from the robot?

Improving decisions via health information technology: Rethinking the architecture of choice

Jessica Ancker, Weill Cornell Medical College
Tuesday, April 4 (12:00 p.m. - 1:15 p.m.)
208 IST Building

Dr. Ancker will outline several recent research projects demonstrating how decisions can be improved by interventions applied to information, information technology, or organizational policy, and discuss pragmatic and ethical implications for healthcare.

Factors influencing outcomes in collaborative writing: An analysis of the processes

Gary Olson, Donald Bren Professor Emerita, Information and Computer Sciences, University of California Irvine
Tuesday, April 4 (3:05 p.m. - 4:20 p.m.)
113 IST Building (Cybertorium)

Today’s commercially available word processors allow people to write collaboratively in the cloud, both in the familiar asynchronous mode and now in synchronous mode as well. This opens up new ways of working together. We examined the data traces of collaborative writing behavior in student teams’ use of Google Docs to discover how they are writing together now. We found that student teams write both synchronously and asynchronously, take fluid roles in the writing and editing of the documents, and show a variety of styles of collaborative writing, including writing from scratch, beginning with an outline, pasting in a related example as a template to organize their own writing, and three more.
