Exploring Active Learning in Meta-Learning: Enhancing Context Set Labeling

Kavli Affiliate: Jing Wang | First 5 Authors: Wonho Bae, Jing Wang, Danica J. Sutherland, , | Summary: Most meta-learning methods assume that the (very small) context set used to establish a new task at test time is passively provided. In some settings, however, it is feasible to actively select which points to label; the […]

Contexts facilitate dynamic value encoding in the mesolimbic dopamine system

Kavli Affiliate: Patricia Janak | Authors: Kurt Michael Fraser, Val L Collins, Amy R Wolff, David J Ottenheimer, Kaisa N Bornhoft, Fiona Pat, Bridget J Chen, Patricia H Janak and Benjamin T Saunders | Summary: Adaptive behavior in a dynamic environment often requires rapid revaluation of stimuli that deviates from well-learned associations. The divergence between […]

Electric fields determine carbapenemase activity in class A β-lactamases

Kavli Affiliate: Michael Beer | Authors: Hira Jabeen, Michael Beer, James Spencer, Marc W van der Kamp, H Adrian Bunzel and Adrian J Mulholland | Summary: MAntimicrobial resistance is a public health crisis. Limited understanding of the catalytic drivers in resistance-mediating enzymes such as β-lactamases hinders our ability to combat this crisis. Here, we dissect […]

Male-male interactions shape mate selection in Drosophila

Kavli Affiliate: Vanessa Ruta | Authors: Tom Hindmarsh Sten, Rufei Li, Florian Hollunder, Shadé Eleazer and Vanessa Ruta | Summary: Males of many species have evolved behavioral traits to both attract females and repel rivals. Here, we explore mate selection in Drosophila from both the male and female perspective to shed light on how these […]
