This allows one to compare several machine learning approaches, as well as to employ some standard techniques of FCA in the domain of machine learning. Algorithmic issues of learning with concept lattices are d
为了使用梯度下降方法训练一个线性回归模型,需要安全计算其损失和梯度。假设学习率为\eta,正则项系数为\lambda,数据集为\{x_{i}^{A}\}_{i\in\mathcal{D}_{A}},\{x_{i}^{B},y_{i}\}_{i\in\mathcal{D}_{B}},模型参数为\Theta_{A},\Theta_{B},分别对应x_{i}^{A},x_{i}^{B}的特...

[…] Often the cause of change is hidden, not known a priori, making the learning task more complicated. — The problem of concept drift: definitions and related work, 2004. The change to the data could take any form. It is conceptually easier to consider the case where there is some ...
The combination of RT-PCR and chest-CT could improve diagnosis performance, but this would requires considerable resources for its rapid use in all patients with suspected COVID-19. The potential contribution of machine learning in this situation has not been fully evaluated. The objective of this...
