Spectra denoising: using graphic cards ?
Abstract
Nuclear Magnetic Resonance and Raman spectra are often noisy, especially for distributed environments. Singular Value Decomposition (SVD) and low-rank approximation are useful tools to denoise spectra. However, processing time can be significantly different depending on which algorithm we use. Java, Matlab and Python were used to compare computation time either from Central Processing Unit (CPU) and Graphics Processing Unit (GPU).
