What does RFE mean in UNCLASSIFIED
Recursive Feature Elimination (RFE) is a feature selection technique used in supervised learning algorithms for reducing the number of input variables. It works by recursively removing attributes and building a model on those attributes that remain. RFE can be used to select features most relevant to the predictive power of a model, which helps reduce noise and overfitting.

What is Recursive Feature Elimination?
Recursive Feature Elimination (RFE) is a feature selection technique used in supervised learning algorithms for reducing the number of input variables. It works by recursively removing attributes and building a model on those attributes that remain.
Why use RFE?
RFE can be used to select features most relevant to the predictive power of a model, which helps reduce noise and overfitting.
How does RFE work?
RFE works by recursively removing attributes from an initial set and then building a model on the remaining attributes. The process continues until only the most relevant features are left or until an acceptable level of accuracy is attained.
What type of learning algorithm is used with RFE?
RFE can be used with any supervised learning algorithm, such as Support Vector Machines (SVM), Decision Trees, Logistic Regression, and Random Forests.
What other techniques are available for feature selection?
Other techniques include Principal Component Analysis (PCA), LASSO Regression, Elastic Net Regularization, and Sequential Forward Selection (SFS).
Final Words:
Recursive Feature Elimination is an effective way to reduce the dimensionality of data by selecting the most meaningful features for a particular predictive task or dataset. When utilized correctly, it can help improve accuracy while limiting overfitting or noise in the data.
