Data preprocessing in Machine Learning refers to the process of preparing the raw data to make it appropriate for a building and training Machine Learning models. In simple words, data preprocessing in Machine Learning nothing but a data mining techniquethat transforms raw data into an understandable and readable format.
Generally, real-world data is inconsistent, incomplete, inaccurate and often lacks specific attribute values/trends. Here is where data preprocessing comes into scenario. In Machine Learning Data Preprocessing is a crucial step that helps improve the quality of data. Data Preprocessing promotes the extraction of meaningful information from the data.
