这是原始英文：
Machine learning is the study of computer algorithms that improve automatically through experience. It is seen
as a subset of artificial intelligence. Machine learning algorithms can be classified as supervised, unsupervised, or reinforcement learning. In supervised learning, algorithms are trained using labeled examples, such as an input where the desired output is known. In unsupervised learning, no labels are given to the learning algorithm, leaving it on its own to find structure in its input. In reinforcement learning, a computer program interacts with a dynamic environment in which it must perform a certain goal (such as driving a vehicle), and must improve its performance over time.
机器学习是通过经验自动提高的计算机算法的研究，被认为是人工智能的一个子集。机器学习算法可分为监督学习、无监督学习和强化学习。在监督学习中，算法使用带标签的示例进行训练，例如已知期望输出的输入。在无监督学习中，没有给出学习算法的标签，使其自行查找输入中的结构。在强化学习中，计算机程序与动态环境互动，必须完成特定目标（如驾驶汽车），并且必须随着时间的推移不断改善其性能。
