Finding Needles in the Haystack: Transductive Active Labeling in Ecology
Researchers have proposed a new approach to active learning for ecological data labeling, arguing that current inductive methods are misaligned with the transductive goal of labeling entire datasets efficiently. The paper highlights that existing methods can underestimate the importance of identifying rare species or behaviors, which are crucial for ecological understanding. To address this, the study introduces a novel metric for sampling difficulty and a hybrid stopping criterion inspired by ecological rarefaction curves, aiming to improve the recovery of rare classes by balancing prediction with discovery.
