Title: Two Simple Topics in Statistical Classification
Speaker: Dr Jing-Hao Xue, Department of Statistical Science, University College London
Abstract:
In this talk I shall first give a brief introduction to University College London (UCL) and her Department of Statistical Science, and then discuss two simple topics in statistical classification: first, why does rebalancing class-unbalanced data improve AUC for linear discriminant analysis, and secondly, how to combine linear discriminative analysis and linear logistic regression to build a better classifier.
