: Measures how close the predicted probabilities are to the actual true frequencies. If you predict a 70% chance of rain, it should actually rain 70% of the time.

: This scent is a reliable field identification mark; for example, the similar Dog Rose ( Rosa canina ) lacks these scent-producing glands. 2. Statistical: The Brier Score Decomposition

The most distinctive "deep" feature of the ( Rosa rubiginosa ) is its scented foliage , which sets it apart from almost all other wild roses. : Measures how close the predicted probabilities are

: Measures how much the predictions differ from the overall base rate. A model that always predicts the average (e.g., 0.5) has no resolution.

In machine learning and forecasting, a "deep feature" of the is its ability to be decomposed into three specific components that explain why a model is performing a certain way: A model that always predicts the average (e

: The undersides of the leaves and the flower stalks (pedicels) are densely covered in tiny, sticky glandular hairs .

: These glands secrete aromatic oils that release a sharp, sweet apple-like fragrance when the leaves are brushed, crushed, or even just dampened by rain. Structural: The "Vine" Monocot

: Represents the inherent randomness of the event itself. This part of the score is independent of the model's performance. 3. Structural: The "Vine" Monocot
