WebAug 4, 2024 · Most machine learning algorithms cannot handle categorical variables unless we convert them to numerical values Many algorithm’s performances even vary … WebThe key takeaways from this article are:-. Categorical variables are mainly in the form of ‘strings’ or ‘categories’ and are finite in number. Two types of categorical data are ordinal and nominal. There are various types of encoding techniques such as label, one-hot, baseN, binary, frequency, effect, and target.
