Your cat recognizer has 15% training error and 16% dev error, but your target is 5% error. What should you do first?

True or False: Adding more training data is an effective technique for reducing high training error caused by high avoidable bias.

Adding more training data is a technique that helps with _____ problems, but it usually has no significant effect on bias.

Your training error is 15% and your target is 5%. What should you focus on first?

True or False: Adding more training data is an effective technique for reducing high avoidable bias.
