For those encountering this term for the first time or those seeking to delve beneath its surface, you’ve embarked on a journey to explore one of the most riveting developments in the tech world.

What is Synthetic Data?

To put it simply, synthetic data is data that isn’t derived from real-world events. Instead, it’s generated through algorithms and computational methods. Think of it as a data twin, mirroring the characteristics of genuine data but without its real-world ties.

In case you’re curious how synthetic data is making waves in the tech world, consider the following:

  • Privacy and Security: In an age where data breaches and privacy concerns are rampant, synthetic data offers a way out. By using synthetic datasets, companies can run tests, develop models, and carry out operations without risking real user data.
  • Cost-Effective Solutions: Imagine the time and resources spent collecting real-world data. Now, compare that to generating a synthetic dataset. The latter is often quicker and more cost-effective.
  • Customized Scenarios: Ever wanted to know how a system would behave in a rare event? With synthetic data, you can model specific scenarios without waiting for them to happen.

“Synthetic data is artificially generated data versus data based on actual events, but it’s not “fake” data. It replicates the properties of real data without the troubles of capturing it, such as confidentiality, low-volume, or expensive-to-validate. With synthetic data, it’s easier and less costly to train AI models, however, it’s not a panacea. For example, synthetic data may not fully represent the unexpected events that happen in the real world.
