数据科学| Stochastic Optimization for AUC Maximization in Machine Learning

时间：12月26日 16:00-17:00报告人：Yiming Ying教授（纽约州立大学奥尔巴尼分校）地点：玉泉工商楼200-9Stochastic optimization algorithms such as stochastic gradient descent (SGD) update the model sequentially with cheap per-iteration costs, making them amenable for large-scale streaming data analysis. However, most of the existing studies focus on the classification accuracy which can not be dir...
