Show answer
Answer
- A The system is a locked AI system whose weights only change through retraining
- C The updated system is considered a new system and requires a fresh round of testing
Explanation
Functions such as traffic sign recognition in cars are safety-related and therefore usually run with locked models. Their weights and bias values are frozen after development and only change through new training. An update is practically a new system and must be tested again.
