Machine learning with big data improves a classification performance but increases computatinal cost for learning. Parallel distributed processing on multiple processors GPUs is often used to reduce processing time. This paper exploits MapReduce, an efficient framework for parallel distributed processing and proposes a novel method for training Random Forests by using the MapReduce framework. At the Map job stage, each worker trains a Transfer Forest with shared data to enhance classification performance. At the Reduce job stage, a reducer removes unreliable decision trees constructed at the Map stage, in order to reduce the computational cost of testing. The proposed method can retain the classification performance, even though unbalanced training samples are assigned to each worker. |
