Toward biologically plausible artificial vision.

Quilty-Dunn et al. argue that deep convolutional neural networks (DCNNs) optimized for image classification exemplify structural disanalogies to human vision. A different kind of artificial vision - found in reinforcement-learning agents navigating artificial three-dimensional environments - can be expected to be more human-like.

Food Insecurity and Mental Distress Among WIC-Eligible Women in the United States: A Cross-Sectional Study.

Background: Women living in Special Supplemental Nutrition Program for Women, Infants, and Children (WIC)-eligible households may be pregnant or breastfeeding.
