让机器自我学习就像每个人在获得技能前,必须经过学习一样,机器要实现智能化,也只能通过学习。机器学习起源于人工智能的一个分支,在这一领域,计算机科学家试图创造计算机的类人智慧。真正的机器学习与我们所认为的传统编程有本质的不同。当提到电脑程序(或者一个程序里用到的运算法则)时,我们一般会认为是工程师为电脑下达了一系列指令,告诉他们怎么样去处理一系列的输入,然后产生相应的输出。但这些都是由人类事先编码好的,而非机器主动学习的结果。 Let the machine self-learning Just as each person must learn before acquiring the skills, the machine must be intelligent and can only be learned. Machine learning has its roots in a branch of artificial intelligence in which computer scientists attempt to create the human-like intelligence of computers. The real machine learning is fundamentally different from what we think of traditional programming. When it comes to computer programs (or algorithms used in a program), we generally think of engineers as issuing a series of instructions to the computer telling them how to handle a series of inputs and then producing the corresponding output. But these are all encoded in advance by human beings, not the result of machine-based learning.
