Description: Value scaling is the process of adjusting the range of data values to a common scale, allowing different features or variables to be comparable to each other. This process is fundamental in data preprocessing, especially in the fields of machine learning and data analysis. By scaling values, the aim is to prevent features with broader ranges from dominating the analysis or model, which could lead to biased or inaccurate results. There are various scaling techniques, such as normalization, which adjusts values to a range between 0 and 1, and standardization, which transforms data to have a mean of 0 and a standard deviation of 1. These techniques enable machine learning algorithms to operate more efficiently and effectively, as many of them assume that data is similarly distributed. In summary, value scaling is a crucial step in data preprocessing that enhances the quality and accuracy of analytical models.
