TL;DR
本文介绍和研究了无限软树集成中的树神经切线核（Tree Neural Tangent Kernel, TNTK），证明了全局收敛以及树结构的等价性，通过调整树的深度诱使TNTK降为退化核。
Abstract
In practical situations, the ensemble tree model is one of the most popular models along with neural networks. A
soft tree
is one of the variants of a decision tree. Instead of using a greedy method for searching splitting rules, the
