机器学习(Machine Learning, ML)是一门多领域交叉学科，涉及概率论、统计学、逼近论、凸分析、算法复杂度理论等多门学科。专门研究计算机怎样模拟或实现人类的学习行为，以获取新的知识或技能，重新组织已有的知识结构使之不断改善自身的性能。

它是人工智能的核心，是使计算机具有智能的根本途径，其应用遍及人工智能的各个领域，它主要使用归纳、综合而不是演绎。-Machine Learning (Machine Learning, ML) is more than one field of cross-disciplinary, involving probability theory, statistics, approximation theory, convex analysis, computational complexity theory and many other subjects. It specializes in computer simulation or how to achieve human learning behavior to acquire new knowledge or skills, reorganize existing knowledge structure so as to continuously improve their performance. It is the core of artificial intelligence, it is to make computers intelligent fundamental way across the various fields of application of artificial intelligence, it is mainly the use of induction, rather than a comprehensive interpretation.
