The Challenge

Understanding human genomic mutations requires analyzing complex, high-dimensional genetic data with multiple interacting factors:

High-dimensional genomic data - Thousands of genetic features with complex interactions
Imbalanced mutation classes - Rare mutations underrepresented in datasets
Complex feature relationships - Non-linear interactions between genetic markers
Interpretability requirements - Medical applications need explainable predictions
Data quality issues - Missing values and noise in genetic sequencing data
Computational complexity - Large-scale genomic datasets require efficient processing
Validation challenges - Need for rigorous cross-validation and biological validation

Required a comprehensive analytical approach with thorough EDA, robust feature engineering, and a hybrid model architecture to capture complex genomic patterns.
