[PDF] Soft Gradient Boosting Machine | Semantic Scholar 速度提升、准确率更胜一筹,周志华等人提出可微XGBoost算法sGBM 并不是很复杂的idea,不过这个多棵并行优化的方式到底能比串行,或半串行快多少是值得怀疑的,毕竟越往右侧还是更多的学习的残差,而前面的树没有很好收敛之前,高阶残差的梯度信号应该没有太多意义...

2 Gradient Boosting算法 任何监督学习算法的目标是定义一个损失函数并将其最小化。 Gradient Boosting 的基本思想是:串行地生成多个弱学习器,每个弱学习器的目标是拟合先前累加模型的损失函数的负梯度,使加上该弱学习器后的累积模型损失往负梯度的方向减少。
Herein, we report an eXtreme Gradient Boosting (XGBoost) machine-learning (ML) model for developing advanced Fe-based MGs with a decent combination of B s and thermal stability. While it is an attempt to apply ML for exploring soft-magnetic property and thermal stability, the developed XGBoost...
Lokanan [15] used a machine learning algorithm to resolve financial fraud disputes, treating disciplinary hearings as a binary classification problem between settlement and contested hearings. They achieved 99% accuracy using the Gradient Boosting classifier for prediction. Chou et al. [16] proposed a...
