Investigating the interplay between AGN coronal properties and hard X-ray variability with NuSTAR

Kavli Affiliate: Claudio Ricci | First 5 Authors: Roberto Serafinelli, Alessandra De Rosa, Alessia Tortosa, Luigi Stella, Fausto Vagnetti | Summary: Active galactic nuclei (AGN) are extremely variable in the X-ray band down to very short time scales. However, the driver of the X-ray variability is still poorly understood. Previous results suggest that the hot […]

Open-Event Procedure Planning in Instructional Videos

Kavli Affiliate: Jing Wang | First 5 Authors: Yilu Wu, Hanlin Wang, Jing Wang, Limin Wang, | Summary: Given the current visual observations, the traditional procedure planning task in instructional videos requires a model to generate goal-directed plans within a given action space. All previous methods for this task conduct training and inference under the […]

Exploration of Class Center for Fine-Grained Visual Classification

Kavli Affiliate: Li Xin Li | First 5 Authors: Hang Yao, Qiguang Miao, Peipei Zhao, Chaoneng Li, Xin Li | Summary: Different from large-scale classification tasks, fine-grained visual classification is a challenging task due to two critical problems: 1) evident intra-class variances and subtle inter-class differences, and 2) overfitting owing to fewer training samples in […]
