FFT-based Dynamic Token Mixer for Vision [PDF]
AAAI Conference on Artificial Intelligence, 2023 Multi-head-self-attention (MHSA)-equipped models have achieved notable performance in computer vision. Their computational complexity is proportional to quadratic numbers of pixels in input feature maps, resulting in slow processing, especially when ...

FFT based approaches in micromechanics: fundamentals, methods and applications
Modelling and Simulation in Materials Science and Engineering, 2021 FFT methods have become a fundamental tool in computational micromechanics since they were first proposed in 1994 by Moulinec and Suquet for the homogenization of composites. Since then many different approaches have been proposed for a more accurate and

HC-FFT: highly configurable and efficient FFT implementation on FPGA
TURKISH JOURNAL OF ELECTRICAL ENGINEERING & COMPUTER SCIENCES, 2021 FFT is one of the basic building blocks in many applications such as sensors, radars, communications. For some applications, e.g., real-time spectral monitoring and analysis, FFT needs to be”run-time configurable” so that the system is real-time. When examining the previous work on configurable real-time (FPGA-based) FFT implementations, we see that ...
