Big data is better da

Big data is better data


Kenneth Cukier從蘋果派談起，
提出
big data
http://en.wikipedia.org/wiki/Big_data
大數據
http://zh.wikipedia.org/wiki/%E5%A4%A7%E6%95%B8%E6%93%9A
對我們的影響:
...more data doesn't just let us see more, more of the same thing we were looking at. More data allows us to see new. It allows us to see better. It allows us to see different.
我們儲存資訊的能力，
相較於4000年前的clay disc，
已大為增加，
同時，
Searching it is easier. Copying it easier. Sharing it is easier. Processing it is easier.
Kenneth Cukier用liquidity to information形容資訊的流通和可變性。
他也舉出Arthur Samuel發明最初的電腦下棋的歷程，
關鍵突破點為:
Arthur Samuel leaves the computer to play itself. It plays itself. It collects more data. It collects more data. It increases the accuracy of its prediction.
因此machine learning創造令人驚奇的成果:
Here's a lot of data around the vehicle. You (The computer) figure it out.
但是Kenneth Cukier也指出
big data有其黑暗面:
1. 個人隱私被收集
2. 許多工作正消失中
他提醒我們要善用科技
We have to be the master of this technology, not its servant.
不要只重視T (technology)
也要多重視更為重要的I (information)。
我們應善用big data，
把它當成tool，
正確使用，
才會有益社會及世界。
