Abstract
As a popular classification algorithm for machine learning, Extreme Learning Machine (ELM) has been widely used. However, its performance on various hardware devices is unclear. According to the baseline implementation of single core ELM, we find that the main time cost of ELM is matrix multiplication. Then, this paper designs various optimized hardware algorithms for several computing devices (Multi-Core, GPU, and FPGA). According to the experiment of each platform, we can see that the speedup ratio of the new hardware platform to ELM is 4~100+, we open our source code and strongly recommend that the later researchers design the application of ELM algorithm based on appropriate hardware platform.
