Evaluating an AI model’s performance is crucial to determine how well it will perform in real-world scenarios. The evaluation helps assess the model’s accuracy, generalization, and robustness, ensuring it will work effectively on new, unseen data. This evaluation process involves measuring performance metrics such as accuracy, precision, recall, and F1-score, helping decide if the model is ready for deployment or needs further refinement.
Give reasons:
(i) The sky appears dark to passengers flying at very high altitudes.
At very high altitudes, passengers are above the atmosphere where there is less scattering of sunlight. As a result, they do not see the scattered blue light and the sky appears dark, similar to the condition experienced by astronauts in space.
(ii) 'Danger' signal lights are red in color.
