Configurable Sensors for Synthetic Data Generation. Solution: As part of the digital transformation process, Manheim decided to change their method of test data generation. However, outliers in the data can be more important than regular data points as Nassim Nicholas Taleb explains in depth in his book, Quality of synthetic data is highly correlated with the quality of the input data and the data generation model. The main reasons why synthetic data is used instead of real data are cost, privacy, and testing. Methodology. Synthetic data is essentially data created in virtual worlds rather than collected from the real world. Producing synthetic data through a generation model is significantly more cost-effective and efficient than collecting real-world data. Synthetic data generation is critical since it is an important factor in the quality of synthetic data; for example synthetic data that can be reverse engineered to identify real data would not be useful in privacy enhancement. We build synthetic, 3D environments that re-create and go beyond reality to train algorithms with an endless array of environmental scenarios, including lighting, physics, weather, and gravity. While this method is popular in neural networks used in image recognition, it has uses beyond neural networks.
