Summary

From building a spam/slop classifier for the Podcast Index, Dave learned that about 90% of model-training work is preparing an excellent training set. A poor, too-small or too-big set makes the model memorize, so you need lots of back-end testing to confirm it generalizes (king is to man as queen is to woman) instead of memorizing (queen = Elizabeth).
