Degradation of Association and Projection White Matter Systems in Alcoholism Detected with Quantitative Fiber Tracking
Alcoholism affected FA and diffusivity, particularly λT, of several fiber bundles. Frontal and superior sites (frontal forceps, internal and external capsules, fornix, and superior cingulate and longitudinal fasciculi) showed greatest abnormalities in alcoholics relative to control subjects.

Using Mixed-Effects Modeling To Analyze Different Grain-Sized Skill Models In An Intelligent Tutoring System
Student modeling and cognitive diagnostic assessment are important issues that need to be addressed for the development and successful application of intelligent tutoring systems (ITS). ITS needs the construction of complex models to represent the skills that students are using and their knowledge states, and practitioners want cognitively diagnostic information at a finer grained level.…

Nanoporous Silica-Water Interfaces Studied By Sum-Frequency Vibrational Spectroscopy
Using sum-frequency vibrational spectroscopy, we found that waterstructure at nanoporous silica/water interfaces depended on the nanoporous film structure.

Co-Adaptation: Adaptive Co-Training for Semi-Supervised Learning
Inspired by popular co-training and domain adaptation methods, we propose a co-adaptation algorithm. The goal is improving the performance of a dialog act segmentation model by exploiting the vast amount of unlabeled data.

Exploiting User Feedback for Language Model Adaptation in Meeting Recognition
We investigate language model (LM) adaptation in a meeting recognition application, where the LM is adapted based on recognition output from relevant prior meetings and partial manual corrections.
