This paper proposed a collaborative filtering regression recommendation algorithm based on extreme learning machine(ELM)and nearest neighbors.The algorithm firstly used the k nearest neighbors method to fill the missing attribute value,then the ELM regression machine is used to produce recommendations for the user.On the benchmarking data sets in the field of recommendation,we compared our algorithm with the common recommend algorithm—LRCF algorithm,and verified the effectiveness of the proposed algorithm.
