Distributions will come up in Loss Functions in Machine Learning (e.g. XGBoost, LightGBM, CatBoost). Selecting the right Loss Function can often improve performance.
Examples:
- Poisson is used for count data.
- Tweedie for mixed continuous data with many zeros like intermittent demand forecasting problems.

"The Tweedie distribution has a point mass at zero before following a 'regular' exponential curve."
