Background:

Gene expression data from high-throughput platforms like microarrays contain significant variation.
This variation can obscure crucial biological information, necessitating effective data preprocessing.
Standard normalization methods often struggle with batch effects and data heterogeneity, impacting downstream analysis.

Purpose of the Study:

To introduce Gene Fuzzy Score (GFS), a novel preprocessing technique for gene expression data.
To evaluate GFS's performance against standard normalization methods using diverse datasets.
To demonstrate GFS's ability to reduce noise while preserving biological signals.

Main Methods:

Gene Fuzzy Score (GFS) was developed as a preprocessing technique.
GFS was compared with three standard normalization methods and raw gene expression data.
Four publicly available datasets with batch effects and heterogeneity were utilized for comparison.

Main Results:

GFS significantly reduced obscuring variation in gene expression data.
GFS outperformed standard normalization techniques in data quality, consistency, and biological coherence.
Processed data using GFS retained valuable biological information.

Conclusions:

Gene Fuzzy Score (GFS) offers a superior alternative to conventional normalization techniques.
GFS effectively makes gene expression values from multiple samples comparable, regardless of platform, batch, or phenotype.
This preprocessing approach enhances the reliability of genomic data analysis across diverse conditions.
