Transferable Clean-Label Poisoning Attacks on Deep Neural Nets
TL;DR: A new "polytope attack" is proposed in which poison images are designed to surround the targeted image in feature space, and it is demonstrated that using Dropout during poison creation helps to enhance transferability of this attack.

R-FCN-3000 at 30fps: Decoupling Detection and Classification
TL;DR: It is shown that the objectness learned by R-FCN-3000 generalizes to novel classes and the performance increases with the number of training object classes - supporting the hypothesis that it is possible to learn a universal objectness detector.
Proceedings ArticleDOI
Learning From Noisy Anchors for One-Stage Object Detection
TL;DR: This paper proposes to mitigate noise incurred by imperfect label assignment such that the contributions of anchors are dynamically determined by a carefully constructed cleanliness score associated with each anchor, and conducts extensive experiments on COCO.

Joint Human Detection and Head Pose Estimation via Multistream Networks for RGB-D Videos
TL;DR: A multistream multitask deep network for joint human detection and head pose estimation in RGB-D videos outperforms state-of-the-art approaches on three public datasets.
