Description: Redundant variables are those that do not provide additional information to a predictive model and can be removed without affecting its performance. In the context of model optimization, identifying and eliminating these variables is crucial, as their presence can introduce noise into the data, complicate analysis, and increase processing time. Redundant variables can arise in various ways, such as including highly correlated variables or duplicating information from different sources. By removing these variables, the model can be simplified, improving its interpretability and, in many cases, increasing its accuracy. Additionally, reducing the dimensionality of the dataset can facilitate the visualization and understanding of underlying patterns. In summary, redundant variables are an important aspect to consider in model optimization, as their removal contributes to the creation of more efficient and effective models.
