Tip 1: Make the labels y consistent
Tip 2: Use multiple labelers to spot inconsistencies
Tip 3: Clarify labeling instructions by tracking down ambiguous examples
Tip 4: Toss out noisy examples. More data is not always better!
Tip 5: Use error analysis to focus on subset of data to improve

Tip 4: Toss out noisy examples. More data is not always better!
Should be rephrased;
Toss out non-decisive/opaque examples while keeping variability of examples.

7.53 The PAC rule doesn't really apply here. What if we are able to label only a few type of easy cases. This means we are not uniformly labelling samples from the original data distribution.
