HBase is the big data store of choice for engineering at HubSpot. It’s a complicated data store with a multitude of levers and knobs that can be adjusted to tune performance. We’ve put a lot of effort into optimizing the performance and stability of our HBase clusters, and recently di...
GBMs, like XGBoost and LightGBM, are powerful for churn prediction but can be complex to tune. Neural networks: Neural networks are deep learning models that can capture complex nonlinear relationships through layers of nodes or “neurons.” They can be very effective, especially with large ...
The typical split is 70% for training to allow the model to learn as much as possible, 15% for validation to tune the parameters, and 15% for testing to evaluate the model’s performance. Feature engineering: This involves selecting, modifying, or creating new features from the raw data ...
