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

Posted by dbos Berkeley

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, […]

Nanomechanical absorption spectroscopy of 2D materials with femtowatt sensitivity

Posted by dbos Delft

Kavli Affiliate: Herre Van Der Zant | First 5 Authors: Jan N. Kirchhof, Yuefeng Yu, Denis Yagodkin, Nele Stetzuhn, Daniel B. de Araújo | Summary: Nanomechanical spectroscopy (NMS) is a recently developed approach to determine optical absorption spectra of nanoscale materials via mechanical measurements. It is based on measuring changes in the resonance frequency of […]

Soliton pulse pairs at multiple colors in normal dispersion microresonators

Posted by dbos Caltech

Kavli Affiliate: Kerry Vahala | First 5 Authors: Zhiquan Yuan, Maodong Gao, Yan Yu, Heming Wang, Warren Jin | Summary: Soliton microcombs are helping to advance the miniaturization of a range of comb systems. These combs mode lock through the formation of short temporal pulses in anomalous dispersion resonators. Here, a new microcomb is demonstrated […]

Mapping the X-ray variability of GRS1915+105 with machine learning

Posted by dbos MIT

Kavli Affiliate: Ronald A. Remillard | First 5 Authors: Benjamin J. Ricketts, James F. Steiner, Cecilia Garraffo, Ronald A. Remillard, Daniela Huppenkothen | Summary: Black hole X-ray binary systems (BHBs) contain a close companion star accreting onto a stellar-mass black hole. A typical BHB undergoes transient outbursts during which it exhibits a sequence of long-lived […]

CodeScore: Evaluating Code Generation by Learning Code Execution

Posted by dbos Peking

Kavli Affiliate: Zhuo Li | First 5 Authors: Yihong Dong, Jiazheng Ding, Xue Jiang, Ge Li, Zhuo Li | Summary: A proper code evaluation metric (CEM) profoundly impacts the evolution of code generation, which is an important research field in NLP and software engineering. Prevailing match-based CEMs (e.g., BLEU, Accuracy, and CodeBLEU) suffer from two […]
