How More Training Data Affects Bias
Question: A team sees that its classifier is unstable on fresh cases and collects additional labeled examples. What is the usual effect of that extra data on the model's bias?
Sample answer: Extra data generally leaves the model's bias unchanged.
Key points:
- More training examples can lower variance.
- More training examples usually do not change bias.
Rubric: The answer must correctly state that adding more training data does not change bias.
