One-hot - Wikipedia

WebOne-hot encoding is a very popular technique used in machine learning to convert categorical data, like red, blue, and green, into binary values of 0 0 and 1 1 for machine learning algorithms to use. NumPy arrays, like any other array, can be indexed based on the indices of the elements. WebBinary encoding introduces false additive relationships between the categories (e.g. category 4 + category 1 = category 5 or 100 + 001 = 101) but fewer of them. Therefore, binary will usually work better than label encoding, however only one-hot encoding will usually preserve the full information in the data.
