題目:如果飛機在飛行當中打一個小洞的話會不會影響飛行的安全呢?
.
選兩個你覺得最有可能的答案
(0)其實狗搖尾巴有很多種方式高興搖尾巴生氣也搖尾巴
(1)如果這個洞的話經過仔細的設計的話應該不至於造成太大問題
(2)所以只要依照政府規定在採收前十天不要噴灑農藥
(3)靜電才是加油站爆炸的元凶手機不過是代罪羔羊
(4)我們可以用表面張力及附著力的原理來測試看看
(5)不過蝦子死亡後身體會釋放出有毒素的體液可能造成水的變質
.
答案請直接拉到最後一段
-----------------------------------
其實我每個周一晚上.....
.
都有偷偷參加Machine Learning的線上讀書會(請勿認親XD)
.
加入已經一年多，今天終於有機會當Host了(感動
.
我就分享一下我今天講的
.
搞不好看完你們就想睡了哈我也算功德無量
.
主題:【自然語言語意分析；Natural Language Processing】
.
簡單來說，電腦可以理解人類很口語的話，電腦也可以透用人類的語法解釋給人類聽電腦自己的想法(output概念)
.
像是siri功能就是
.
你跟siri講「我明天要7:30起床」跟「早上7:30分叫我」
-->siri都會幫你設早上7:30分的鬧鐘
.
表示 siri她聽得懂你很口語，亂七八糟的，非結構化的語意!!!!!
.
廢話不多說，我們直接來跑程式
.
(0)環境jupyter notebook python 3.6.3
.
(1) 下載一份語料('cna.cbow.cwe_p.tar_g.512d.0.txt')

https://mega.nz/#!5LwDjZia!f77y-eWm90H3akg8mD9CqhOZ89NihirRKN4IT1SJ01Q
.
【圖1】每一個詞都有一個介於0~1的分數，分數越接近表示他們的意思越相近，
像是「柯文哲」可能是0.0000420，「市長」可能是0.0000428;
像是「快樂」可能是0.0000123，「高興」可能是0.0000124
.
(2)下載jieba numpy
語法:
import jieba
import numpy as np
.

(3)把cna.cbow.cwe_p.tar_g.512d.0.txt解析後存成word_vecs物件
.
(4)給電腦題目:"如果飛機在飛行當中打一個小洞的話會不會影響飛行的安全呢?
.
給電腦6個選項問他哪一個是對的
.
(5) 【圖2】電腦會給六個答案，每個答案都會有一個介於0~1的數字，數字最大的選項，就是電腦的答案!
.
電腦會選:如果這個洞的話經過仔細的設計的話應該不至於造成太大問(分數0.632分)
.
我們可以用表面張力及附著力的原理來測試看看(分數0.57分)
.
(6)結論就是: 電腦答對了!! 🤣😃

大家晚安
