This week I presented “Introduction to Machine Learning with XGBoost” to my stats colleagues. Why do I want to learn XGBoost and introduce to other statisticians? XGBoost is one of the most popular machine learning algorithms these days. It has won the RAAD (Roche Advanced Analytics Data) challenge among 81 teams across 19 Roche sites in early 2018! Among the 81 teams, different methods (including logistic regression) have been tried, the top 3 teams all used XGBoost!
I just returned from PSI conference 2018. I got a chance to give an oral present at session “Step into the Real World”. I shared my experience from taking part in Roche Advanced Analytics Data (RAAD) Challenge. The take-home message is “with available wealthy real-world data and the power of machine learning for such data, statisticians would be benefit to know machine learning methods”.
