With the development of mobile high-speed access networks, network traffic increased significantly, but mobile terminal so that computing and storage is limited, making large data mining applications with limited artificial intelligence, cloud computing can be advantageous to resolve such conflicts, improve user experience. Due to this problem, the paper with cloud computing and big data mining joint consideration is designed on mobile Internet features of large data mining algorithm, and giving full consideration to the data transfer efficiency and topology mobile access, the simulation results show the algorithm effectiveness.
