Synthetic Data
Synthetic data is data generated by a model or simulation rather than collected from the real world. It is used to train or test AI systems when real data is scarce, sensitive, or hard to obtain.
In Simple Terms
Think of it as a flight simulator for AI: practice on artificial scenarios when the real ones are costly or rare.
Detailed Explanation
Synthetic data can be produced by rule-based generators, GANs, diffusion models, or LLMs. Use cases include training with more examples, balancing classes, preserving privacy (no real PII), and stress-testing edge cases. Quality varies: good synthetic data should be representative and not introduce subtle biases. As generation improves, synthetic data is increasingly used in computer vision, NLP, and tabular data. It complements rather than replaces real data when ground truth and diversity matter.

Transfer learning is the practice of taking a model already trained on one task or dataset and reusing or adapting it for another. It speeds development and often improves performance when data for the new task is limited.
