What is synthetic data?

Synthetic data is essentially data generated by algorithms or computer models to mimic real-world data without being direct copies of it. This machine-generated data possesses similar statistical properties and patterns as the original data, but it doesn't correspond directly to any specific records in the real-world dataset.

Key points about synthetic data:

• Machine-generated: It is created through computational methods such as machine learning models rather than collected from real-world events 1 2.
• Same features, not the same records: Synthetic data replicates the features and properties of real data but ensures that each synthetic sample doesn’t directly match any unique real-world sample. It maintains the overall distribution and relationships within the dataset 1.
• Applications in AI and ML: It is useful for training models, especially when there is a lack of sufficient real data. Synthetic data can augment datasets to improve model training and robustness 3 4.

• Privacy: Since synthetic data doesn't contain real-world information, it can be used to address privacy concerns, allowing for data analysis and model training without exposing sensitive information 5.
• Challenges: Creating synthetic data that is as diverse and messy as real-world data can be difficult. Ensuring the synthetic data has enough variability and captures the nuances of real-world data is a significant challenge 2.

By generating data that looks and behaves like real-world data, synthetic data enables robust model training and testing while safeguarding privacy and addressing data scarcity issues.
