Witryna9 kwi 2024 · Discrete data are whole numbers or integers that can be counted and are finite. Continuous data are quantifiable and expressed as fractions or decimals. Bar graphs are a typical representation of discrete data. Continuous data use a histogram. The values don’t break down into more discrete subdivisions. Witrynaclass sklearn.preprocessing.OrdinalEncoder (categories=’auto’, dtype=) [source] Encode categorical features as an integer array. The input to this transformer should be an array-like of integers or strings, denoting the values taken on by categorical (discrete) features. The features are converted to ordinal integers.
