Parallel Training GBRT Based on KMeans Histogram Approximation for Big Data Learning To Rank(LTR) benchmark datasets and the large-scale real-world datasets from Baidu search engine. The experimental results show that our proposed parallel training algorithm outperforms the state-of-the-art parallel GBRT algorithm with near 2 times speedup and better accuracy. Also, our algorithm achieves the near-linear scalability.

Feature Selection Method Based on Feature’s Classification Bias and Performancevectorization representation of feature’s classification ability is beneficial for those partially predominant features winning out. Also multi-features’ classification redundancies are easily measured in the new space. Experimental results demonstrate the effectiveness of the new method on both low-dimensional and high-dimensional data.
