Abstract:In principal component analysis, data logarithm transformation and row vector centralization improvement are carried out, reducing the input, and simplifying the network model. Use sparrow search algorithm for optimization, and compare the performance with cuckoo algorithm, seagull algorithm, and whale algorithm. To avoid problems as slow convergence speed and insufficient exploration ability, an improved sparrow search algorithm integrating refraction inverse learning mechanism, sin-cosine and Cauchy variatio… Show more
