Decision Intelligence and Why Goldilocks Made Bad Choices
Spoiler: Goldilocks survives. Let us first start by saying things could have turned out much worse. Really worse. Don’t walk into a stranger’s house and eat their food and nap in their house. This is just a no-brainer! In the real world when we make decisions there is a much... Read more
Using the NGBoost Algorithm
Data scientists competing in Kaggle competitions often come up with winning solutions using ensembles of advanced machine learning algorithms. One particular model that is typically part of such ensembles is Gradient Boosting Machines (GBMs). Gradient boosting is a machine learning method used for the solution of regression and classification... Read more

XGBoost: Enhancement Over Gradient Boosting Machines
In the first part of this discussion on XGBoost, I set the foundation for understanding the basic components of boosting. In brief, boosting uses sequences of decision trees that seek to reduce the residuals of the prior tree. In other words, each new tree uses the residual of the... Read more
