Spring is approaching, it is the time for your good ideas to spring out :)


The topic of of this week is logistic regression(LR), here are some highlights,


Wanqi            --   Introduction to LR: From linear regression to logistic regression


Xingyuan       --   Parallelizing LR using MapReduce and Its commercial applications


Lunchao        --   Applications of LR in modeling categorical response, ordinal variables and cases control studies

Section A. 由初等到高等,介绍线性回归的三种诠释:

1. 初等几何上的解释 - 求数据点的投影平面。Closed Form Solution
2. 分析上的解释 - 求凸优化问题的解, Least Mean Squared (LMS)
3. 统计上的解释 - Maximum Likelihood (ML)

Section B. Logistic Regression的概率定义。

Section C. Generalized Linear Model 与基于Bayesian Statistics的Regularization.
