Background:

Microarray data analysis presents a high-dimensional challenge.
Weakly relevant or redundant features can negatively impact classifier performance.

Purpose of the Study:

To develop a novel algorithm for redundant feature selection.
To improve the accuracy of tumor classification using microarray data.

Main Methods:

Propose RESI (Redundant fEature Selection depending on Instance), a supervised algorithm.
RESI measures feature subset redundancy incorporating label information.
Addresses limitations of previous methods that only considered feature relationships.

Main Results:

RESI demonstrates superior performance compared to state-of-the-art algorithms.
Experimental results on benchmark datasets validate RESI's effectiveness.
Achieves better results than mRMR (minimum Redundancy Maximum Relevance) in redundant feature selection.

Conclusions:

RESI is an effective supervised method for redundant feature detection.
The proposed method enhances tumor classification accuracy.
Highlights the importance of considering label information in feature selection.
