Description: K-means feature selection is a technique that combines K-means clustering with feature selection to identify and retain the most relevant variables in a dataset. This approach is particularly useful in the context of machine learning with large datasets, where the number of features can be overwhelming and often includes redundant or irrelevant information. By applying the K-means algorithm, data is grouped into clusters based on similarities, allowing for the identification of patterns and relationships among features. Subsequently, the importance of each feature is evaluated based on its ability to differentiate between the formed clusters. This process not only improves model efficiency by reducing dimensionality but can also enhance accuracy by eliminating noise and less significant features. K-means feature selection is especially valuable in scenarios involving substantial volumes of data, such as data mining, image analysis, and natural language processing, as it enables machine learning models to focus on the variables that truly impact model performance.
