Evaluating Performance Gains in Model Training
An AI development team uses a small, fast model to provide training labels for a much larger, more powerful model. After this training process, they observe that the powerful model's accuracy on a specific task improves by 15 percentage points. Explain why this 15-point improvement, on its own, is insufficient to judge the effectiveness of this training strategy. What two additional performance metrics would be essential for a more meaningful evaluation?

Formula for Performance Gap Recovered (PGR)
An AI research team conducts two separate experiments to improve a powerful model's performance by having it learn from a less powerful one. The results are as follows:
- Experiment A: The less powerful model scores 50% on a task. The powerful model, after learning from the less powerful one, scores 70%. The powerful model's maximum possible score on this task is 90%.
- Experiment B: The less powerful model scores 70% on a different task. The powerful model, after learning from the less powerful one, scores 78%. The powerful model's maximum possible score on this task is 80%.
Based on these results, which experiment demonstrates a more effective transfer of knowledge from the less powerful model to the more powerful one, in terms of closing the potential performance gap?
