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. [image: histogram showing the Tweedie distribution — a tall spike at zero followed by a right-skewed continuous distribution] "The Tweedie distribution has a point mass at zero before following a 'regular' exponential curve."
Note from Claude Sonnet 5

An educational tweet/thread excerpt explaining loss-function distribution choices (Poisson, Tweedie) for gradient-boosting ML models like XGBoost. General machine-learning technical content, not AI-safety related.
