Assessing Students. Performance Longitudinally: Item Difficulty Parameter Vs. Skill Learning Tracking
We are engaged in an effort to investigate if we can do a better job of predicting a large scale test (MCAS) by modeling individual skills in different grain-sized skill models than by using item difficulty parameters induced from traditional Item Response Theory models, on which computer adaptive testing relies.

Towards Live Informing and Automatic Analyzing of Student Learning: Reporting in the Assistment System
In this article we describe the types of reports that we have designed and implemented that provide real time reporting to teachers in their classrooms. Experiment analysis tools are available to facilitate researchers to carry out randomized controlled learning experiments so that they are able to compare different tutoring strategies.

NAP and WCCN: Comparison of Approaches Using MLLR-SVM Speaker Verification System
We compare two recently proposed techniques, within class covariance normalization (WCCN) [1] and nuisance attribute projection (NAP) [2], for intersession variability compensation in speaker verification.

Statistical Sentence Extraction for Information Distillation
In this paper, we present a statistical sentence extraction approach for distillation. Basically, we frame this task as a classification problem, where each candidate sentence in documents is classified as relevant to the query or not.

Balancing push and pull for efficient information discovery in large-scale sensor networks
Abstract In this paper, we investigate efficient strategies for supporting on-demand information dissemination and gathering in large-scale wireless sensor networks. In particular, we propose a “comb-needle” discovery support model resembling an ancient method: use a comb to help find a needle in sand or a haystack. The model combines push and pull for information dissemination…
