Edges in a social graph may represent private information that needs to be protected. Due to their graph partition schemes, existing edge anonymization methods have several drawbacks, such as high utility loss and high computational overhead. In this paper, we present a new edge anonymization method, which partitions a graph using a new vertex equivalence relation called the neighbor-set equiva...

The current study examined if low social support is a shared risk factor for both disorders among adolescent girls and boys. This study is a part of the Adolescent Mental Health Cohort Study's two-year follow-up. We st...

We extend a recent formalization of multi-agent plan recognition (MAPR), to accommodate compact multi-agent plan libraries in the form of context free grammars (CFG), incomplete plan executions, and uncertainty in the observation trace. Some existing approaches for single agent plan recognition cast it as a problem of parsing a single agent activity trace. With the help of our multi-agent CFG, ...

To increase college access and reduce the burden of student loan debt, the US government has developed several new tuition and student loan policies. These include the newly proposed free community college plan and the recently enacted Pay As You Earn plan that makes student loan repayments contingent on earnings. I develop and estimate a dynamic life-cycle model of the decisions individuals ma...
