Efficient logic architecture in training gradient boosting decision tree for high-performance and edge computing

Autor: Tanaka, Takuya, Kasahara, Ryosuke, Kobayashi, Daishiro

This study proposes a logic architecture for the high-speed and power efficiently training of a gradient boosting decision tree model of binary classification. We implemented the proposed logic architecture on an FPGA and compared training time and p
