Abstract

Aiming at the limitation that the existing big data classification methods cannot meet the time and storage space in big data applications, this paper proposed a design method of big data parallel multi-label K-nearest neighbor classifier based on Apache Spark framework. In order to reduce the cost of the existing MapReduce scheme by using other memory operations, firstly, it divided the training set into several partitions in conjunction with the parallel mechanism of the Apache Spark framework. Then in the map stage, it found the K-nearest neighbors of each partition of the sample to be predicted, and in the reduce phase, it determined the final K-nearest neighbors according to the results of the map phase. Finally, it aggregated the neighboring tag sets in parallel, and output the target tag set of the sample to be predicted by maximizing the posterior probability. Experiments were carried out on four big data classification datasets such as PokerHand. The proposed method achieves a lower Hamming loss and proves its effectiveness.
