Effect of Adding Training Data on Model Bias
Question: When a practitioner decides to add more training data to resolve high variance in a machine learning model, what is the typical effect of this addition on the model's bias?
Sample answer: Adding training data to address variance usually does not affect the model's bias.
Key points:
- Adding training data reduces variance.
- Adding training data does not affect bias.
Rubric: The answer must correctly state that adding training data does not affect or change bias.
