Abstract  To address the issue of overly heavy computational load of extreme learning machine(ELM) in the big data environment, parallel optimization for ELM is studied. A multi-partition relaxed alternating direction method of multipliers(ADMM) for regularized ELM along with two scalarwise implementations in the N- and N/2-equipartition cases is proposed. By the multi-partition, the proposed algorithm has a highly parallel structure and the combination with relaxation technique improves the convergence rate of the proposed algorithm. Through analysis, a necessary and sufficient convergence condition is established, and optimal convergence ratio and optimal parameters are obtained. Through simulations on bench-mark datasets, the relationship between the convergence ratio and the number of partitioned blocks is calculated, and convergence rates and GPU acceleration ratios of different algorithms are compared. Experimental results demonstrate that the proposed algorithm has low computational complexity and high parallelism.
