计算学习理论中的一个关键见解是，学习问题的复杂性由假设空间的复杂性和可用数据的数量决定。
"A key insight in computational learning theory is that the complexity of a learning problem is determined by the complexity of the hypothesis space and the amount of data available."
Man is so naturally good that when he does evil it is against his will.
化学的进步以新元素的发现和分析方法的改进为标志。
The greatest glory in living lies not in never falling, but in rising every time we fall.
