Sentiment analysis invites us to consider the sentence, You’re so smart! and discern what’s behind it. It sounds like quite a compliment, right? Clearly…

Following best practices when building machine learning models is a time-consuming yet important process. There are so many things to do ranging from: preparing the data, selecting and training algorithms, understanding how the algorithm is making decisions, all the way down to deploying models to production. I like to think of the machine learning design and maintenance process as being…

***Spoilers Ahead***   This blog is meant to be a fun and unique take on predicting which characters are likely to survive (or die) in the final season of "Game of Thrones".   After finishing season seven of Game of Thrones, the record-breaking HBO show based on George R. R. Martin’s fantasy series A Song of Ice and Fire, we…

We've gotten some questions recently about how much data is needed to train a good model. While there is no "one-size-fits-all" approach, there are some general best practices to follow and questions to ask about your data beforehand. Ryan elaborates. How much data do you need to train a model? Arguably, only a single data point. Is this model likely…

Gradient Boosted Regression Trees (GBRT) or shorter Gradient Boosting is a flexible non-parametric statistical learning technique for classification and regression. This notebook shows how to use GBRT in scikit-learn, an easy-to-use, general-purpose toolbox for machine learning in Python. We will start by giving a brief introduction to scikit-learn and its GBRT interface. The bulk of the tutorial will show how…
