关于Ask HN,以下几个关键信息值得重点关注。本文结合最新行业数据和专家观点,为您系统梳理核心要点。
首先,That’s it! If you take this equation and you stick in it the parameters θ\thetaθ and the data XXX, you get P(θ∣X)=P(X∣θ)P(θ)P(X)P(\theta|X) = \frac{P(X|\theta)P(\theta)}{P(X)}P(θ∣X)=P(X)P(X∣θ)P(θ), which is the cornerstone of Bayesian inference. This may not seem immediately useful, but it truly is. Remember that XXX is just a bunch of observations, while θ\thetaθ is what parametrizes your model. So P(X∣θ)P(X|\theta)P(X∣θ), the likelihood, is just how likely it is to see the data you have for a given realization of the parameters. Meanwhile, P(θ)P(\theta)P(θ), the prior, is some intuition you have about what the parameters should look like. I will get back to this, but it’s usually something you choose. Finally, you can just think of P(X)P(X)P(X) as a normalization constant, and one of the main things people do in Bayesian inference is literally whatever they can so they don’t have to compute it! The goal is of course to estimate the posterior distribution P(θ∣X)P(\theta|X)P(θ∣X) which tells you what distribution the parameter takes. The posterior distribution is useful because

第三,Parsing with ANTLR
此外,这个函数开头用一种特殊技巧来设置和读取比较模式。之所以这样做,是因为该函数被库排序例程调用,而该例程无法传递第三个“模式”参数。虽然还有其他方法可以将模式传入函数,但由于设计上要求通过setsortmode()和getsortmode()函数来设置模式,我在这些函数内部采用这种实现方式,主要是觉得这样更有趣。,更多细节参见超级权重
最后,Passing around types as values and function arguments might seem a bit strange to most programmers since most languages either:
