What we're about

Visit our new site at https://nyhackr.org/

Meet with other users of the open-source programming language R. Previously, this meetup focused only on the R language, but is now focused on all open-source data analysis tools; including but not limited to, Python, Julia, C++, Stan, etc.

Learn and share tricks and techniques from and with other users. Beginners to advanced users are all welcome.

Comparing {lightgbm} to other R GBDT Libraries

Online event

For this meetup we turn to LightGBM, a competitor to xgboost and catboost.

Thank you to EcoHealth Alliance for providing the Zoom link.

Conversations during the meetup are encouraged in the monthly-meetup-chat channel in the nyhackr slack: https://nyhackr.org/slack.html

About the Talk:
In this talk, attendees will learn about LightGBM, a popular gradient boosted decision tree (GBDT) framework. The talk begins with an overview of LightGBM and the features that allow it to be fast without sacrificing accuracy. After those fundamentals, attendees will learn about how {lightgbm} compares to two other popular GBDT projects with R packages: {catboost} and {xgboost}. That portion of the talk will cover why you might choose one library over the others, and will discuss issues ranging from ease-of-installation and data loading to algorithmic details like handling of sparse features and strategies used to decide which splits to evaluate.
