In the context of computational learning, the concept of 'probably approximately correct' (PAC) learning provides a framework for understanding the efficiency and feasibility of learning algorithms.
在计算学习的背景下，“可能近似正确”（PAC）学习的概念为理解学习算法的效率和可行性提供了一个框架。
The only real failure in life is not to be true to the best one knows.
The truth is rarely pure and never simple.
The quality of your attention determines the quality of your life.
O poder das palavras está na sua capacidade de criar mundos inteiros.
