Modularity is essential for building large systems, as it allows us to break down complex problems into smaller, more manageable parts.

The challenge in computational learning theory is to understand the capabilities and limitations of learning algorithms.

A good algorithm is like a sharp knife—it does exactly what it is supposed to do with a minimum of effort.

There is no such thing as great wisdom in the world, just as there is no such thing as talent. What exists is triviality. If you keep doing repetitive things, you become an expert; if you do repetitive things with special focus, you become a master.

成功来自于关注长期，而不仅仅是短期收益。
