What is label encoding and how does it convert non-numerical data into numerical form?

Monday, 07 August 2023 by EITCA Academy

Label encoding is a technique used in machine learning to convert non-numerical data into numerical form. It is particularly useful when dealing with categorical variables, which are variables that take on a limited number of distinct values. Label encoding assigns a unique numerical label to each category, allowing machine learning algorithms to process and analyze
