Description: Value transformation is a fundamental process in data preprocessing that involves applying mathematical functions to modify the distribution of values in a dataset. This process is crucial for preparing data before analysis, as it allows for the normalization, standardization, or transformation of variables to meet the requirements of machine learning algorithms and statistical analysis. By applying transformations, the aim is to improve data quality, reduce the influence of outliers, and facilitate model convergence. Transformations can include operations such as scaling, where values are adjusted to a specific range, or applying logarithmic and exponential functions to handle skewed distributions. Proper value transformation not only optimizes model performance but can also reveal hidden patterns in the data that might otherwise go unnoticed. In summary, value transformation is a critical stage in the data analysis workflow, ensuring that the data is suitable for subsequent analysis and that the results are more accurate and meaningful.
