Lesson 5 - 貝葉斯規則

使用癌癥案例

有一種特定的癌癥 在人群中的發(fā)病率為 1%

這種癌癥的一種化驗,有 90% 的幾率,在得了這種癌癥的情況下呈**,這通常被叫做 敏感度(Sensitivity)

但有時(shí)候即便沒(méi)有得癌癥,化驗也呈**,比如 另外有 90% 的幾率,沒(méi)有得癌癥的情況下呈陰性,這通常被叫做 特異度(Specitivity)

那么對于以下問(wèn)題:

在沒(méi)有其他癥狀的情況下 你進(jìn)行了化驗,結果呈**

你認為的這種特定類(lèi)型癌癥的概率是多少？

要回答這個(gè)問(wèn)題 我們先畫(huà)個(gè)圖

假設這些是所有人,其中剛好有 1% 得了癌癥,99% 沒(méi)得癌癥

我們知道有一種化驗,如果你得了癌癥,可以有 90% 的幾率正確診斷出來(lái), 如果我們畫(huà)出化驗呈**的區域 (紅色陰影部分)

但是 這并不是全部的真實(shí)情況,化驗還有可能在沒(méi)有癌癥的,情況下呈**, 實(shí)際上 在我們的例子里,這占所有情況的 10%,因此 我們必須添加更多區域,就是這個(gè)大的區域的10%,這里化驗結果可能在沒(méi)有癌癥的情況下,呈**( 藍色陰影部分 ). 很顯然 這些圓圈外的所有區域,對應沒(méi)得癌癥并且,化驗呈陰性的情況

 

 

下面首先了解一些基本術(shù)語(yǔ).

先驗概率( Prior probability ) : 進(jìn)行化驗之前的概率

后驗概率( posterior probability ) : 通過(guò)化驗得到一些證據, 這樣我們就得到了所謂的后驗概率

貝葉斯法則( Bayesion rule ) 可以將化驗中得到的一些證據, 納入你的先驗概率中,并得到后驗概率

例如, 在癌癥的例子中, 癌癥的 先驗概率(Prior probability) 為1%, 患癌癥并且檢測為**的概率為90%.

對于 后驗概率(posterior probability) , 我們的問(wèn)題是由**來(lái)推出得癌癥得概率, 因此要包括兩部分, 一部分是 得癌癥呈現**得概率 , 另一部分是 沒(méi)有得癌癥呈現**得概率.

那么計算可得:

然后對兩部分進(jìn)行 歸一化(Normalization) , 在這個(gè)例子中表示 測試結果為** , 也就是上圖中藍色區域加紅色區域組成得 橢圓部分

對于之前的先驗概率其實(shí)嚴格講為兩個(gè)事件的 聯(lián)合概率(Joint Probability) , 最后得到 化驗結果為**時(shí)得癌癥的后驗概率 , 就必須用 測試為**得到癌癥的概率0.009 除以 Normalizer = 0.108

我們剛剛說(shuō)過(guò) 有一種情況

例如 當你收到 **化驗結果 時(shí) 你要做的是:

現在 你計算出了期望的后驗概率

這就是貝葉斯法則的算法

對應到之前畫(huà)的示意圖中可得下圖

練習

示意圖如下

提示，貝葉斯法則如下所示:

我們可以將貝葉斯法則中的 A 和B 替換掉，顯示為：

​

現在，我們了解先驗概率和條件概率后，可以改寫(xiě)為：

不過(guò)我們還不知道一件事！我們看見(jiàn)紅色的概率是多少？ 答案是 0.5。

全概率法則

機器人看到紅色有以下兩種情況。

由此得出答案：

The following questions will help you review what you learned in the Bayes' Rule lesson.

For questions 1-3, assume you already have the following knowledge:

You’re interested in finding out the probability of a car stopping if it sees a yellow traffic light.

習題 1/5

When a car is stopped at an intersection, data shows that 12% of the time the light is yellow. So if we know a car is stopped, there's a 12% chance the light is yellow. This is called a conditional probability.

Given P(S) and P(Y) above, how would you represent this conditional probability in notation?

習題 2/5

Using what you know from question 1, answer the following: if the traffic light is yellow, what is the chance that the car will stop?

And intuitively this value seems about right; a car should stop about half the time when faced with a yellow light.

習題 3/5

Knowing that a car stopping at an intersection and the presence of a yellow traffic light are related events, what are P(S) and P(Y) known as?

Prior knowledge for question 4:

On a four-lane highway, cars are either going fast or not fast. Faster cars should go in the leftmost lanes.

習題 4/5

Given the above information, if a car is going fast, what is the probability that it will be in the leftmost lane?

Bayes' rule is not only used to incorporate sensor data into an estimate; it’s also often used to incorporate test data into a medical diagnosis.

Prior knowledge for question 5:

習題 5/5

Given the above data, what is the probability that a person has cancer if they have a positive cancer-test result? (Note: answers are rounded to the nearest 4th decimal place).

請問(wèn)una corda 是什么意思

una corda〔意〕（原意：一根弦）（1）在一根弦上演奏（弦樂(lè )器）。（2）用弱音踏板，參見(jiàn)tre corde

una corda :

The soft pedal (or una corda pedal) is one of the standard pedals on a piano, generally placed leftmost among the pedals. On a grand piano, this pedal shifts the whole action including the keyboard slightly to the right, so that hammers that normally strike all three of the strings for a note strike only two of them. This softens the note and also modifies its tone quality.
