Boot strapping the dictionary meaning is to start up with minimum resources. In the Context of an OS the OS should be able to swiftly load once the Power On Self Test (POST) determines that its safe to wake up the CPU. The boot strap code will be run from the BIOS. BIOS is a small sized ROM. Generally it is a jump instruction to the set of instructions which will load the Operating system to the RAM. The destination of the Jump is the Boot sector in the Hard Disk. Once the bios program checks it is a valid Boot sector which contains the starting address of the stored OS, ie whether it is a valid MBR (Master Boot Record) or not. If its a valid MBR the OS will be copied to the memory (RAM)from there on the OS takes care of Memory and Process management.

为了完整起见，它也是统计学中一个相当重要的(相对较新的)方法，它使用重采样/模拟从样本中推断总体属性。它在维基百科上有一篇关于自我引导(统计)的长篇文章。

亚历克斯，这和你的电脑启动时做的差不多。('Booting' a computer实际上来自于单词bootstrapping)

最初，运行BIOS中的小程序。它包含足够的机器代码来加载和运行一个更大、更复杂的程序。

第二个程序可能是类似于NTLDR(在Windows中)或LILO(在Linux中)的程序，然后执行并能够加载，然后运行操作系统的其余部分。

术语“自举”通常适用于系统依赖自身启动的情况，有点像鸡和蛋的问题。

例如:

如何编译用C编写的C编译器? 如果操作系统还没有运行，如何启动操作系统初始化进程? 如何启动一个分布式(点对点)系统，在这个系统中，客户端依赖于它们当前已知的对等点来查找系统中的新对等点?

在这种情况下，bootstrapping指的是一种打破循环依赖关系的方法，通常借助外部实体的帮助。

您可以使用另一个C编译器来编译(引导)您自己的编译器，然后您可以使用它来重新编译自己 您使用一段单独的代码来设置初始进程，而不依赖于操作系统提供的任何函数 您使用硬编码的初始对等体列表或提供对等体列表的硬编码跟踪器URL

etc.

除了它在软件开发中的应用(例如kdgregory给出的答案)和Dirk Eddelbuettel所讨论的在统计学中的应用之外，在强化学习的上下文中，Bootstrapping还有另一个对开发人员有用的含义。

来自萨顿和巴托:

Widrow, Gupta, and Maitra (1973) modified the Least-Mean-Square (LMS) algorithm of Widrow and Hoff (1960) to produce a reinforcement learning rule that could learn from success and failure signals instead of from training examples. They called this form of learning “selective bootstrap adaptation” and described it as “learning with a critic” instead of “learning with a teacher.” They analyzed this rule and showed how it could learn to play blackjack. This was an isolated foray into reinforcement learning by Widrow, whose contributions to supervised learning were much more influential.

这本书描述了各种强化算法，其中目标值是基于先前的近似作为bootstrap方法:

最后，我们注意到 DP[动态规划]方法的最后一个特殊性质。所有这些都更新了估计 基于对继承者价值的估计的状态值 州。也就是说，他们在其他数据的基础上更新估计 估计。我们把这叫做引导。许多钢筋 学习方法执行引导，即使是那些没有引导的方法 要求，正如DP要求，一个完整和准确的模型 环境。

请注意，这不同于维基百科页面上提到的自举聚合和智能爆炸。

As a humble beginner in the world of programming, and flicking through all the answers here after seeing this word used a lot in apparently slightly different ways in different places, I found reading the Wikipedia page on Bootstrapping (duh! I didn't think of it either at first) is very informative to understand differences in use of this word. Could it be......on extremely rare occasions......Wikipedia might even have better explanations of certain terms than....(redacted)? Will they bring in rep points on Wikipedia though?

对我来说，似乎所有的意义都与:从尽可能简单的东西开始，用Thing2做一些稍微复杂的东西，现在你可以用Thing2比原来的Thing1更有效、更快地完成某些任务。然后从第二件事重复到第三件事，直到无限……

I see it as closely connected to both biological evolution and 'Layers of Abstraction' (newbies like me see, ahem, Wikipedia, cough) - the evolution from 1940's computers with switches, machine code, Assembly, C, Python, AIs you can give all kinds of complex instructions to like "make the %4^% dinner to my default &^$% requirements and clean the floor you %$£"@:~" in drunken slang English or Amazon tribal dialect without them 'raising an exception' (for newbies again...you guessed it) - missed out lot of links there due to simple ignorance.

那么在某些特定的软件意义上: 含义1:Thing1用于加载Thing2的最新版本(因为Thing2当然会比Thing1大，就像Thing3会比Thing2大一样)。

Meaning2: Thing1 is a lower level language (closer to 1001011100....011001 than print("Hello, ", user.name)) used to write a little bit of the higher language of Thing2, then this little bit of Thing2 is used to expand Thing2 itself from baby vocabulary level towards adult vocabulary level (Thing2 starts to be processed, or to use correct technical term 'compiled', by the baby version of itself (it's a clever baby!), whereas the baby version of Thing2 itself could of course only be compiled by Thing1, cause it can't exist before it exists, right duh!), then child version of Thing2 compiles Surly Teenager version of Thing2, at which point programming community decides whether Surly Teenager's 'issues' (software term and metaphor term!) are worth spending enough time resolving to be accepted long term, or to abandon them to (not sure where to take the analogy here).

如果是，那么Thing2已经“bootstrap”自己(可能有几次)从婴儿到成年:“孩子是男人的父亲”(华兹华斯，建议不要试图在Stack Overflow上查找引用或作者)。
