Prior to study at Lehigh, I earned my undergraduate degree in Control Science and Engineering from Chu KoChen Honors College in Zhejiang University, Hangzhou, China. During summer I worked at industrial research labs on projects in different fields such as ads targeting, machine learning, hierarchical classifications, time series forecasting, traffic control, etc.



Distributed L-BFGS on Apache Spark

An efficient algorithm for optimizing large-scale regularized functions. Current C/C++ (with MATLAB interface) implementations can handle

The algorithm/implementation can be easily extended to deal with smooth loss functions other than least square and logistic loss. See for yourself.
