Item statistics derived from three-option versions of multiple-choice questions are usually as robust as four- or five-option versions: implications for exam design. [PDF]

open access: yes, 2018
Different versions of multiple-choice exams were administered to an undergraduate class in human physiology as part of normal testing in the classroom. The goal was to evaluate whether the number of options (possible answers) per question influenced the ...

Molecular Nanoarchitectonic Sensing Layer for Analysis of Volatile Fatty Acids in Bioreactor Headspaces Using a Nanomechanical Sensor

open access: yesAdvanced Materials Technologies, EarlyView.
A porous crystalline sensing layer has been developed in conjunction with a nanomechanical sensor for the sensitive detection of volatile fatty acids (VFAs) in admixture at high relative humidity. The sensitive, selective sensor based on supramolecular design improves the economic viability of anaerobic digesters toward a carbon neutral society ...

The effects of stimulus variability on the perceptual learning of speech and non-speech stimuli.

open access: yesPLoS ONE, 2015
Previous studies suggest fundamental differences between the perceptual learning of speech and non-speech stimuli. One major difference is in the way variability in the training set affects learning and its generalization to untrained stimuli: training ...

Learning Discriminators as Energy Networks in Adversarial Learning [PDF]

open access: yesarXiv, 2018
We propose a novel framework for structured prediction via adversarial learning. Existing adversarial learning methods involve two separate networks, i.e., the structured prediction models and the discriminative models, in the training. The information captured by discriminative models complements that in the structured prediction models, but few ...

Progress in Surface Plasmon and Other Resonance Biosensors for Biomedical Applications

open access: yesAdvanced Materials Technologies, EarlyView.
This is the shortened version: Recent advancements in surface plasmon resonance and other optical resonance biosensors for biomedical applications are presented. Advanced sensing strategies are examined for the detection of diverse analytes, integration of nanomaterials and machine learning, and emerging nonplasmonic modes like guided mode resonance ...

Avoiding Discrimination through Causal Reasoning

open access: yes, 2018
Recent work on fairness in machine learning has focused on various statistical discrimination criteria and how they trade off. Most of these criteria are observational: They depend only on the joint distribution of predictor, protected attribute ...
