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."
The difference between a dream and reality is action.
La joie de l'âme est dans l'action.
每一个想法都是适应之舞的一步。
Avoid extreme ideologies because they rob you of your sanity.
