Machine learning yields unpredictable results. It's not a bug. It's pattern recognition. It's just not always the pattern you intended to be recognized.

Case example. The army trained a neural network to determine whether or not pictures contained images of tanks. It had 100% accuracy in the test data, but only 50% accuracy afterwards. The reason? All the test images that had tanks in them were taken on a cloudy day, and the non-tank pictures on a sunny day. The neural network learned to detect cloudy days, not tanks.

Machine learning may involve learning unintended and arbitrary things.

The Housing Trap
You're being set up to spend your life paying off a debt you don't need to take on, for a house that costs far more than it should. The conspirators are all around you, smiling to lure you in, carefully choosing their words and watching your reactions as they push your buttons, anxiously waiting for the moment when you sign the papers that will trap you and guarantee their payoff. Don't be just another victim of the housing market. Use this book to defend your freedom and defeat their schemes. You can win the game, but first you have to learn how to play it.
