Evaluating Models’ Local Decision Boundaries via Contrast Sets

Findings, 2020
Standard test sets for supervised learning evaluate in-distribution generalization. Unfortunately, when a dataset has systematic gaps (e.g., annotation artifacts), these evaluations are misleading: a model can learn simple decision rules that perform ...

Spectral triangulation molecular contrast optical coherence tomography with indocyanine green as the contrast agent [PDF]

, 2004
We report a new molecular contrast optical coherence tomography (MCOCT) implementation that profiles the contrast agent distribution in a sample by measuring the agent's spectral differential absorption.

Crystal structure of diethyl 3,3′-[(4-nitrophenyl)methylene]bis(1H-indole-2-carboxylate)

Acta Crystallographica Section E: Crystallographic Communications, 2017
In the title compound, C29H25N3O6, the mean planes of the two indole ring systems (r.m.s. deviations = 0.0115 and 0.0082 Å) are approximately perpendicular to one another, making a dihedral angle of 89.7 (5)°; the benzene ring is twisted with respect to ...

Underwater Image Restoration and Enhancement Based on a Fusion Algorithm With Color Balance, Contrast Optimization, and Histogram Stretching

IEEE Access, 2021
A fusion algorithm is proposed for the restoration and enhancement of underwater images. Color balance, contrast optimization and histogram stretching are carried out. To alleviate the effect of color shift in an underwater image, the scalar values of R,

Association of Maximal Extent of Resection of Contrast-Enhanced and Non-Contrast-Enhanced Tumor With Survival Within Molecular Subgroups of Patients With Newly Diagnosed Glioblastoma.

JAMA Oncology, 2020
Importance Per the World Health Organization 2016 integrative classification, newly diagnosed glioblastomas are separated into isocitrate dehydrogenase gene 1 or 2 (IDH)-wild-type and IDH-mutant subtypes, with median patient survival of 1.2 and 3.6 years,

Stressed vowel duration and phonemic length contrast [PDF]

, 2012
As far as phonemic length contrast is concerned, we observe a high degree of durational overlap between phonemically long and short vowels in monosyllabic CVC words (which is enforced by a greater pitch excursion), whereas in polysyllables the ...

Contrasting contrastive-topicalization strategies

Anuario del Seminario de Filología Vasca "Julio de Urquijo", 2023
This paper offers a comparison and preliminary analysis of ‘topicalization’ strategies in German, Basque, and English. I argue that Basque and English topics at the left periphery are dislocated elements resumed by pronominal correlates, a configuration more directly evidenced in German.
