I worked as an assistant analyst and developer at Baidu, a Chinese leading search engine company, from Apr. 2014 to Aug. 2014. I had a memorable and valuable experience there. I was mainly responsible for the automatized statistical modeling of A/B test, which is commonly used in the online advertisement evaluation. Here is a slide of brief introduction on what I did(the work has already been filed into a patent, and the slide doesn't show more about its public information).
