The article highlights the critical roles of data transformation and discretization within the data preprocessing pipeline. By addressing the inherent issues related to raw data - such as noise and inconsistency - these processes prepare the data for effective analysis. Key transformation techniques discussed include normalization, aggregation, and discretization, each playing a crucial part in enhancing data quality and interpretability. The necessity of these techniques not only boosts the efficiency of data mining algorithms but also facilitates deeper insights into the processed data.
Data transformation is vital for converting raw, noisy, and inconsistent data into formats suitable for analysis, ensuring improved accuracy and efficiency in data mining.
Techniques such as smoothing, normalization, and discretization play key roles in enhancing data quality and interpretability, allowing algorithms to work more effectively.
