Semantic-Guided Generative Image Augmentation Method with Diffusion Models for Image Classification

Kavli Affiliate: Feng Wang | First 5 Authors: Bohan Li, Xiao Xu, Xinghao Wang, Yutai Hou, Yunlong Feng | Summary: Existing image augmentation methods consist of two categories: perturbation-based methods and generative methods. Perturbation-based methods apply pre-defined perturbations to augment an original image, but only locally vary the image, thus lacking image diversity. In contrast, […]

Faithful and Consistent Graph Neural Network Explanations with Rationale Alignment

Kavli Affiliate: Xiang Zhang | First 5 Authors: Tianxiang Zhao, Dongsheng Luo, Xiang Zhang, Suhang Wang, | Summary: Uncovering rationales behind predictions of graph neural networks (GNNs) has received increasing attention over recent years. Instance-level GNN explanation aims to discover critical input elements, like nodes or edges, that the target GNN relies upon for making […]

Graphene-driven correlated electronic states in one dimensional defects within WS$_2$

Kavli Affiliate: Michael F. Crommie | First 5 Authors: , , , , | Summary: Tomonaga-Luttinger liquid (TLL) behavior in one-dimensional systems has been predicted and shown to occur at semiconductor-to-metal transitions within two-dimensional materials. Reports of one-dimensional defects hosting a Fermi liquid or a TLL have suggested a dependence on the underlying substrate, however, […]

Continuous Trajectory Optimization via B-splines for Multi-jointed Robotic Systems

Kavli Affiliate: Ting Xu | First 5 Authors: Changhao Wang, Ting Xu, Masayoshi Tomizuka, , | Summary: Continuous formulations of trajectory planning problems have two main benefits. First, constraints are guaranteed to be satisfied at all times. Secondly, dynamic obstacles can be naturally considered with time. This paper introduces a novel B-spline based trajectory optimization […]
