🧮 Data, features and labels

Unit 2 · How AI works · 9 min

Machine learning learns from examples. Each example has features (a fruit's colour, weight) and a label ("apple" or "orange"). More accurate, more varied data gives a better model; biased data gives a biased model.

Words in this lesson

• 数据 (shù jù) — data
• 标签 (biāo qiān) — label
• 偏差 (piān chā) — bias

Project: Design a small table: 10 fruits with 3 features and 1 label each.
