On the Noisy Gradient Descent that Generalizes as SGD
Jingfeng Wu, Wenqing Hu, Haoyi Xiong +3
The gradient noise of SGD is considered to play a central role in the observed strong generalization abilities of deep learning. While past studies confirm that the magnitude and t…

Quasi-potential as an implicit regularizer for the loss function in the stochastic gradient descent
Wenqing Hu, Zhanxing Zhu, Haoyi Xiong +1
We interpret the variational inference of the Stochastic Gradient Descent (SGD) as minimizing a new potential function named the \textit{quasi-potential}. We analytically construct…

FWDA: a Fast Wishart Discriminant Analysis with its Application to Electronic Health Records Data Classification
Haoyi Xiong, Wei Cheng, Wenqing Hu +2
Linear Discriminant Analysis (LDA) on Electronic Health Records (EHR) data is widely-used for early detection of diseases. Classical LDA for EHR data classification, however, suffe…
