What You Know About Deep Learning Is A Lie

Last Updated on August 19, 2019 Getting started in deep learning is a struggle. It’s a struggle because deep learning is taught by academics, for academics. If you’re a developer (or practitioner), you’re different. You want results. The way practitioners learn new technologies is by developing prototypes that deliver value quickly. This is a top-down approach to learning, but it is not the way that deep learning is taught. There is another way. A way that works for top-down practitioners like you. In this […]

Tune Learning Rate for Gradient Boosting with XGBoost in Python

Last Updated on August 27, 2020 A problem with gradient boosted decision trees is that they are quick to learn and overfit training data. One effective way to slow down learning in the gradient boosting model is to use a learning rate, also called shrinkage (or eta in XGBoost documentation). In this post you will discover the effect of the learning rate in gradient boosting and how to tune it on your machine learning problem using the XGBoost library in […]

Stochastic Gradient Boosting with XGBoost and scikit-learn in Python

Last Updated on August 27, 2020 A simple technique for ensembling decision trees involves training trees on subsamples of the training dataset. Subsets of the the rows in the training data can be taken to train individual trees called bagging. When subsets of rows of the training data are also taken when calculating each split point, this is called random forest. These techniques can also be used in the gradient tree boosting model in a technique called stochastic gradient boosting. […]
