Forage-plot soil-grade is poor, fair, good, excellent. Integer ranks preserve that order. Using the same integers on unordered berth names would invent a false rank. When is label encoding correct?

Short Explanation

Think of soil-grade poor, fair, good, excellent. Integer ranks preserve that order. The same integers on unordered berth names invent a false rank. Label encoding is only for ordered categories.

Full Explanation

Label or ordinal encoding is correct only when the category is ordered. Soil-grade is that case. The same integers on unordered berth names invent a false rank. Rekognition is not an encoder.
