FLDATN: Black‐Box Attack for Face Liveness Detection Based on Adversarial Transformation Network
International Journal of Intelligent Systems, Volume 2024, Issue 1, 2024.Aiming at the shortcomings of the current face liveness detection attack methods in the low generation speed of adversarial examples and the implementation of white‐box attacks, a novel black‐box attack method for face liveness detection named as FLDATN is proposed based on adversarial transformation network (ATN).

Removing the anonymity axiom in assessing pro-poor growth [PDF]
The recent focus on ‘pro-poor growth’ led also to an intense debate on how exactly to define and to measure pro-poor growth. However, all suggested measures, irrespective whether they use the absolute or the relative definition of pro-poor growth have in
