Representative Synthesized Training Examples
When synthesizing data, one should consider whether the synthesized examples are representative. Synthesized data should avoid properties that make it possible for a learning algorithm to distinguish synthesized from non-synthesized examples, such as all synthesized car data coming from 20 car designs or all synthesized audio coming from only 1 hour of car noise.
