Automatic Optimization of DSP Algorithms
… code. Timings are compared, using fast Fourier transform (FFT), Walsh-Hadama transform (WHT), discrete cosine transform (DCT) and discrete sine transform (DST) as the benchmarks, to those obtained by highly optimized implementations including FFTW and the WHT package. The results of this …

Low-Complexity Structured Neural Networks and Their Usage in Image and Signal Processing
… of sparse and self-contained factorizations of transforms, with applications to image compression, reconstruction, classification, encryption, and also adaptive wideband multi-beam beamforming. The first neural network architecture, named DCTrix-Net, replaces conventional spatial con- volution …
