A statistical method for massive data based on partial least squares algorithm

Partial least squares are the most widely used identification algorithm, but the algorithm cannot achieve real-time performance for massive data. To solve this application contradiction, a parallel computing strategy based on NVIDIA CU-DA architecture is proposed to implement the partial least squares algorithm using a graphics processor (GPU) with massively parallel computing features as the computing device and combining the advantages of GPU memory. Research and analysis found that the partial least squares algorithm implemented using CUDA on GPU is 48 times faster than the implementation of the CPU. Therefore, the algorithm has good usability and higher application value, which makes it possible to apply the partial least squares algorithm to massive data statistics. © 2023 Yan Xu, published by Sciendo.
