최대 사후 확률(最大事後確率, maximum a posteriori, MAP)은 베이즈 통계학에서 사후 확률(事後確率)의 최빈값을 가리킨다. 최대 사후 확률에 대응하는 모수(母數, Parameter)는 최대우도(最大尤度, maximum likelihood estimation, MLE)와 마찬가지로 모수의 점 추정으로 사용할 수 있지만, 최대우도에서는 어떤 사건이. Maximum Likelihood Estimation은 우리가 어떤 parameter를 추정할 때, likelihood 값을 최대로 하는 parameter를 찾는 과정을 말한다.하지만 Maximum Likelihood Estimation은 우리가 기본적으로 알고 있는 데이터의 사전 지식 정보는 반영하지 못한다는 한계를 가진다. 이러한 단점을 극복하고, 우리가 데이터에 대한 정보가. ** 바로 ML(Maximum Likelihood) 방법과 MAP(Maximum A Posteriori) 방법이다**. 관측값을 z, 그 값이 나온 클래스(또는 모델)를 x라 하자. 예를 들어, 바닥에 떨어진 머리카락의 길이(z)를 보고 그 머리카락이 남자 것인지 여자 것인지 성별(x)을 판단하는 문제를 생각해 보자

Maximum a Posteriori를 설명하기 전에 먼저 Posteriori 에 대한 설명이 필요하다. 일반적으로 동전을 던졌을 때, 질량의 분포가 균등하게 이루어져 있다면 앞면이 나올 확률은 0.5 라고 알고 있다. 이 말이 검증 하기 위해 동전을 100번 던졌다 Maximum A Posteriori (MAP) Estimation. The MAP estimate of the random variable X, given that we have observed Y = y, is given by the value of x that maximizes. f X | Y ( x | y) if X is a continuous random variable, P X | Y ( x | y) if X is a discrete random variable. The MAP estimate is shown by x ^ M A P . To find the MAP estimate, we need to. * Maximum a Posteriori 위 식의 왼쪽절편이 사후분포 (posteriori)라고 불린다*.

Map provides an alternate Probability framework for Maximum likelihood estimation for. Maximum a Posteriori Maximum a posteriori estimation - Wikipedi . In Bayesian statistics, a maximum a posteriori probability (MAP) estimate is an estimate of an unknown quantity, that equals the mode of the posterior distribution.The MAP can be used to obtain a point estimate of an unobserved quantity on the basis of empirical data A priori and a posteriori ('from the earlier' and 'from the later', respectively) are Latin phrases used in philosophy to distinguish types of knowledge, justification, or argument by their reliance on empirical evidence or experience. A priori knowledge is that which is independent from experience.Examples include mathematics, tautologies, and deduction from pure reason 最大后验（英文为Maximum a posteriori，缩写为MAP）. 举个例子：数字通信系统中，最大后验概率准则是指在接收到混合波形后，判断出发送信号的条件概率密度最大。. 由于它是在收到混合波形后才具备的，故称为后验概率（或概率密度）。. 看看统计学的书就知道.

The maximum a posteriori estimation, also known as a MAP estimate, is the mode (most frequent value) of a statistical distribution. In terms of a classification problem, this value would represent the most probable class label for a given piece of data.
