In the context of enhancing model performance through feature selection in your machine learning project, which Databricks MLlib-supported technique is adept at identifying the most pertinent features from a vast dataset?
Explanation:
Recursive Feature Elimination (RFE) stands out as the correct choice. This technique, supported by Databricks MLlib, excels in selecting the most relevant features by iteratively training the model and pruning the least significant features. Through this recursive process, RFE efficiently hones in on the feature subset that maximizes model performance, making it an invaluable tool for feature selection in machine learning projects.
