One-hot Encoding is a technique used to convert categorical variables into binary vectors that can be used in machine learning algorithms. It involves representing each category as a unique binary value, where only one bit is "hot" (1) and the rest are "cold" (0).
One-hot Encoding works by creating separate binary columns for each category in a categorical variable. If a data point belongs to a certain category, the corresponding binary column will be set to 1, while the rest of the columns will be set to 0. This allows machine learning algorithms to process categorical data as numerical data.
One-hot Encoding is important because many machine learning algorithms can only process numerical data. By converting categorical variables into binary vectors, One-hot Encoding enables these algorithms to effectively process and analyze categorical data. It helps in capturing the information present in categorical variables, which can be critical for accurate predictions and insights.
One-hot Encoding is commonly used in various fields and applications, including:
One-hot Encoding is closely related to other data encoding and representation techniques, including:
