On Scalable Inference with Stochastic Gradient Descent

no code implementations1 Jul 2017 Yixin Fang, Jinfeng Xu, Lei Yang

In many applications involving large dataset or online updating, stochastic gradient descent (SGD) provides a scalable way to compute parameter estimates and has gained increasing popularity due to its numerical convenience and memory efficiency.

Sparse Convex Clustering

1 code implementation18 Jan 2016 Binhuan Wang, Yilong Zhang, Will Wei Sun, Yixin Fang

Convex clustering, a convex relaxation of k-means clustering and hierarchical clustering, has drawn recent attentions since it nicely addresses the instability issue of traditional nonconvex clustering methods.
