2. Challenges in AI and ML Integration in Genomics

Despite the transformative potential of AI and ML in genomics, several challenges must be

addressed to realize their benefits fully:

• Data Quality and Availability: High-quality, annotated genomic datasets are essential for training accurate AI models. However, obtaining such datasets can be challenging due to issues like data fragmentation, varying data formats, and limited availability of large-scale datasets.

• Interpretability: AI and ML models often operate as “black boxes,” making it challenging to interpret their decisions. In genomics, it is crucial to understand why a particular genetic variant is associated with a disease or how a model arrived at a specific prediction. Research efforts are ongoing to develop explainable AI models in genomics to enhance transparency and trust.

• Generalization: AI models trained on specific populations or datasets may not generalize well to diverse populations, leading to biased predictions. Ensuring the inclusivity and diversity of genomic data used for training AI models is vital to avoid biased outcomes.

3. Future Prospects of AI and ML in Genomics

The future of AI and ML in genomics holds immense promise, which includes:
