LEARNING IS INFERRING THE GRAMMAR OF A DOMAIN
Characteristic of the human species is a relentless search for abstract rules,high-level conclusions that are extracted from a specific situation and subsequently tested on new observations. Attempting to formulate such abstract laws can be an extraordinarily powerful learning strategy, since the most abstract laws are precisely those that apply to the greatest number of observations. Finding the appropriate law or logical rule that accounts for all available data is the ultimate means to massively accelerate learning -and the human brain is exceedingly good at this game.
Let us consider an example. Imagine that I show you a dozen opaque boxes filled with balls of different colors. I select a box at random, one from which I have never drawn anything out before. I plunge my hand into it, and I draw a green ball. Can you deduce anything about the contents of the box?What color will the next ball be?
学习就是推断出某一领域的法则
人类的特点就是无休止地寻找抽象的规则，从具体情况下提取出来，接着又在新环境下检验的高级结论。尝试将这种抽象的规则公式化可能是特别有利的学习策略，因为最抽象的规则正是那些可以在最多数环境下使用的。找到能适用于所有可获得数据的合适的规则或逻辑法则是可以大规模加速学习的终极手段---而人类大脑特别擅长这件事。
我们考虑一个事例。想象一下我指给你看一打不透明的盒子，里面装的是不同颜色的球。我随机选择盒子，一个盒子我之前没有取出来任何东西。我把手放进去，取出来一个绿色球。你能推断盒子里的东西吗？下一个球什么颜色？
