Generalizing Face Forgery Detection with High-frequency Features [PDF]
Computer Vision and Pattern Recognition, 2021 Current face forgery detection methods achieve high accuracy under the within-database scenario where training and testing forgeries are synthesized by the same algorithm. However, few of them gain satisfying performance under the cross-database scenario

Simulation of TiN/HfO2/Pt memristor I–V curve for different conductive filament thickness [PDF]
Modern Electronic Materials, 2021 The operation of the TiN/HfO2/Pt bipolar memristor has been simulated by the finite elements method using the Maxwell steady state equations as a mathematical basis.

Improving Vision Transformers by Revisiting High-frequency Components [PDF]
European Conference on Computer Vision, 2022 The transformer models have shown promising effectiveness in dealing with various vision tasks. However, compared with training Convolutional Neural Network (CNN) models, training Vision Transformer (ViT) models is more difficult and relies on the large ...

Detecting high-frequency gravitational waves with microwave cavities [PDF]
Physical Review D, 2021 We give a detailed treatment of electromagnetic signals generated by gravitational waves (GWs) in resonant cavity experiments. Our investigation corrects and builds upon previous studies by carefully accounting for the gauge dependence of relevant ...

U-Sleep: resilient high-frequency sleep staging
npj Digital Medicine, 2021 Sleep disorders affect a large portion of the global population and are strong predictors of morbidity and all-cause mortality. Sleep staging segments a period of sleep into a sequence of phases providing the basis for most clinical decisions in sleep ...

Quantifying the High-Frequency Trading "Arms Race"
Quarterly Journal of Economics, 2021 We use stock exchange message data to quantify the negative aspect of high-frequency trading, known as “latency arbitrage.” The key difference between message data and widely familiar limit order book data is that message data contain attempts to trade

Efficient Frequency Domain-based Transformers for High-Quality Image Deblurring [PDF]
Computer Vision and Pattern Recognition, 2022 We present an effective and efficient method that explores the properties of Transformers in the frequency domain for high-quality image deblurring. Our method is motivated by the convolution theorem that the correlation or convolution of two signals in ...
