Stretching Domain Adaptation: How far is too far?

While deep learning has led to significant advances in visual recognition over the past few years, such advances often require a lot of annotated data. While unsupervised domain adaptation has emerged as an alternative approach that doesn’t require as much annotated data, prior evaluations of domain adaptation have been limited to relatively simple datasets. This work pushes the state of the ar...

Active commuting to school: How far is too far?

BACKGROUND Walking and cycling to school provide a convenient opportunity to incorporate physical activity into an adolescent's daily routine. School proximity to residential homes has been identified as an important determinant of active commuting among children.

How many steps along the path is too far?

Neely et al [1] have studied the disposition of voriconazole in children suspected or proven to have a fungal infection. Although this is important, and the pharmacokinetic data are most welcome in this difficult-to-study population, the ability to link the drug concentrations observed to outcome is the critical issue for this study. A number of other investigators have linked measures of voric...
