Cancer Diagnosis through Contour Visualization of Gene Expression Leveraging Deep Learning Techniques.

Area of Science:

• Bioinformatics
• Computational Biology
• Genomics

Background:

• Accurate cancer diagnostics and therapy rely on gene expression data analysis.
• Integrating analytical methods improves detection by revealing complex data patterns.

Purpose of the Study:

• To develop a diagnostic-integrated approach for cancer detection using gene expression data.
• To combine Empirical Bayes Harmonization (EBS), Jensen-Shannon Divergence (JSD), deep learning (DL), and contour mathematics.

Main Methods:

• Empirical Bayes Harmonization (EBS) for data preprocessing.
• Jensen-Shannon Divergence (JSD) to measure distributional differences between sample types.
• Deep learning (DL) for automated feature extraction and pattern recognition.
• Contour mathematics for visualizing decision boundaries in high-dimensional space.

Main Results:

• JSD effectively guides DL models to focus on cancer-specific features.
• Contour visualization enhances the interpretability of the DL model's decision-making process.
• The integrated approach demonstrates potential for precise cancer detection.

Conclusions:

• The combined JSD, DL, and contour mathematics method offers a promising strategy for cancer diagnostics.
• This approach leverages DL for feature extraction and JSD for identifying key distributional shifts.
• The method provides valuable insights for timely diagnosis and personalized cancer treatment.
