Abstract	In machine learning, high-quality datasets are essential for accurate predictions, but many fields like healthcare and finance face data scarcity, imbalance, and collection challenges, leading to poor model performance. Synthetic data mimics real-world data and has emerged as a solution to augment small datasets, improve diversity, and address underrepresented classes. It also mitigates privacy concerns in sensitive domains. Techniques like Generative Adversarial Networks (GANs) use a generator and discriminator to create realistic synthetic data, while Variational Autoencoders (VAEs) encode and decode data to generate new points. Methods like SMOTE address class imbalances by creating synthetic samples. These advancements enable better model performance without relying solely on costly or hard-to-collect real-world data, benefiting critical applications in healthcare, finance, and beyond.
