超級比一比
by c3h3
特別感謝....
為什麼要比價?
系統架構
Crawler
AI
Kernel
App
(Service)
ghost.py
從 Business Model
開始思考......

其實 ......
還有很多沒講出來的問題

另一個範例
感謝大家!
願意讓一個沒修過半門統計課的大學生,來負責設計商品比對的核心算法!
並且,感謝兩位老闆
願意讓我來 PyCon 分享公司商品的部份核心
價格變動超快!!
當紅的 pi 價錢也跳超快的!
數小時之中
可以連續上下震盪 10%
瞬間跌 15%
這種波動率
台股都自嘆不如
價格變動快速
變動幅度超大
Business Model?
兩個比價前輩
的故事
公司網址:http://www.getpentagon.com.au/
歡迎大家幫我們介紹需要比價的澳洲廠商
從前輩的身上學到:
訪價系統?
比對系統?
調價系統?
傳統的 Solution
如果........
pyv8
BeautifulSoup
NumPy
SciPy
CVXOPT
打造 Matching Kernel
時所遭遇的問題
NLTK
Big Data:
(Product Pairs)
1K X 1K = 1百萬
10K X 10K = 1億
Tornado
Pairwise ~ O(N^2)
Labeling Problems:
(1) O(N^2) Teaching Pairs ?
(2) Label Propagation ?
(3) Labeling 標準問題 ?
NetworkX
有點難 Model 成
傳統的 MLDM 問題:
Supervised ?
Unsupervised ?
最終模型必須要能:
(1) 包含 Heuristic Model
(2) Labeling Feedback
(3) 依據不同使用者的標記,而動態創造不同模型!
打造 Matching Kernel
