Sep 28, 2021 · One-hot encoding is used to convert categorical variables into a format that can be readily used by machine learning algorithms. The basic idea of one-hot encoding is to create new variables that take on values 0 and 1 to represent the original categorical values. For example, the following image shows how we would perform one-hot encoding to convert a categorical variable that contains team names into new variables that contain only 0 and 1 values:

Jul 26, 2020 · One-Hot Encoding Concepts Simply speaking, one-hot encoding is a technique which is used to convert or transform a categorical feature having string labels into K numerical features in such a manner that the value of one out of K ( one-of-K) features is 1 and the value of rest (K-1) features is 0.

The features are encoded using a one-hot (aka ‘one-of-K’ or ‘dummy’) encoding scheme. This creates a binary column for each category and returns a sparse matrix or dense array (depending on the sparse parameter) By default, the encoder derives the categories based on the unique values in each feature.
