Here I've sorted some recent projects and publications.

Transfer and Active Learning (ONR Guided Learning)

This is a recentfly finished five year project that produced many publications for transfer learning and active learning. A common thread was easier to ask active learning questions and transfer learning in various settings. Example publications:

IJCAI 2013 Active learning from relative queries

ICDM 2016 Transfer Regession with relative queries

Active Transfer Learning for Intelligent Tutoring (ONR)

In this project we are working with a company (SOARTECH) to explore the suitability of our work on active and transfer learning to the intelligent tutoring problem. Here the problem is to access the skill level for a student on a variety of related skils but minimizing the number of questions asked of the student.

Functional Network Discovery for Brain Connectivity (NSF)

In this project we explore spatial temporal data which can be considered as being a movie of the same spatial region over time. We attempt to simplify this data into what we term networks which are regions of interest (ROI) which behave cohesively and the relationships between those regions. This problem can be formulated a number of ways as a constrained spectral clustering problem, a tensor decomposition problem and a block model problem.
