Synchrony of Anterior Cingulate Cortex and Insular-Striatal Activation Predicts Ambiguity Aversion in Individuals with Low Impulsivity
To test how dACC functional network connectivity would be modulated by uncertainty and differ between individuals, 24 healthy participants underwent functional MRI in 3 sequential runs: 1 resting-state and 2…

Towards Quantifying the Completeness of BDI Goals
We sketch a pragmatic but principled mechanism for quantifying the level of completeness of goals in a Belief-Desire-Intention--like agent.

Blended Learning Report
With funding from the Michael & Susan Dell Foundation, SRI’s Center for Technology in Learning studied the adoption of blended learning models in selected schools in California and Louisiana associated…

On the Feasibility of Deploying Cell Anomaly Detection in Operational Cellular Networks
In this paper, we build on our previous work and study the feasibility of an operational deployment of an adaptive ensemble-method framework for modeling cell behavior.

Unscented Transform for iVector-Based Noisy Speaker Recognition
In this paper, it is proposed to substitute the first order VTS by an unscented transform, where unlike VTS, the nonlinear function is not applied over the clean model parameters…

Effective Use of DCTS for Contextualizing Features for Speaker Recognition
This article proposes a new approach for contextualizing features for speaker recognition through the discrete cosine transform (DCT).

Effects of Thermal Treatment on Radiative Properties of HVPE Grown InP Layers
We have studied radiative properties of 21 micron thick InP layers grown by HVPE and found them comparable to those of best luminescent bulk InP virgin wafers. This opens up…

Forensic Prescreening System Using Coded Aperture Snapshot Spectral Imager
We present a camera system for instantaneous, non-destructive capture of spectral signatures for forensic analysis. Our system detects highly probative samples in the forensic scene mixed by the multiple target…

Late Fusion and Calibration for Multimedia Event Detection Using Few Examples
In this paper, we present two parametric approaches to late fusion: a normalization scheme for arithmetic mean fusion (logistic averaging) and a fusion scheme based on logistic regression, and compare…

Studies of a Prototype Linear Stationary X-Ray Source for Tomosynthesis Imaging
A prototype linear x-ray source to implement stationary source–stationary detector tomosynthesis (TS) imaging has been studied.

Calibration and Multiple System Fusion for Spoken Term Detection Using Linear Logistic Regression
This study presents an efficient and effective score calibration technique for keyword detection that is based on the logistic regression calibration approach commonly used in forensic speaker identification.

Adaptive and Discriminative Modeling for Improved Mispronunciation Detection
In the context of computer-aided language learning, automatic detection of specific phone mispronunciations by nonnative speakers can be used to provide detailed feedback about specific pronunciation problems.
