Multi-armed bandits are a reinforcement learning tool often used in environments where the cost or rewards of different choices are unknown or where those functions may change over time.

Building an open source library is not unlike building a democracy. The citizens of the programming community can freely choose whether or not to use the library, as well as how and whether to contribute back to the project.

When we think about what Python is for, we often think of things like analytics (SciPy, NumPy, Pandas), machine learning (scikit-learn, PyTorch, Keras), and web apps (Django, Flask).

Modeling is often treated as a search activity: find some combination of features, algorithm, and hyperparameters that yields the best score after cross-validation.
