a rust library for efficient histogram approximations
This rust library based on the paper: A Streaming Parallel Decision Tree Algorithm written by Ben-Haim & Yom-Tov's.
Benchmark Environment
Laptop : MacBook Pro (13-inch, 2018, Four Thunderbolt 3 Ports)
Processor: 2.3 GHz 4 Intel Core i5
Memory : 16 GB 2133 MHz LPDDR3
As the benchmark result list below, if you set the bucket size to 50,the average time cost for each add operation will cost 400-500ns ( >2,000,000 op/s).
