夢想‧Schoolala 番外篇
Look at “Economic Tsunami” from “Machine Learning”
日期:2009年3月29日(星期日)
時間:下午2:15至4:30
地點:紅磡理工大學 Core R, 4/F, Rm406
主持:William Hui (中文大學畢業Scholar,現攻讀工程學博士)
去年William主持了兩次工作坊。第一次在Schoolala的舞台上,向初中生大談哲學,大談蘇格拉底,教人津津樂道; 第二次在ExCo和Board member的分享會上,用兩張A4紙,寫了兩個英文字:“Conformity”&“Individuality”,便足夠談了一小時,精彩絕侖。
這次再請William辦個工作坊,內容要 illustrate他從事的科研項目,對象是我們Scholars。
要求他用最簡單易明的方法來表達那抽象的研究主題,是一項挑戰。他說:「講History吧!」我大惑不解:「History跟你的工作有關嗎?」他回答:「History is more related to what happened around us, but you know my work is what is around us, so is it ok? Don’t you think we live in quite a drastic era?」
太玄了。
幾天後,收到William回覆:「Ok, I changed my mind. I will explain the current “economic tsunami” using the concept of “overtraining” in my work of “machine learning”.」
“Economic Tsunami” 和 “Machine Learning” , 我一下子聯繫不上。
“Overtraining happens when the learner thinks he has learned something when he should not have. He probably has learned something unlearnable, but believes instead that ‘wow I know this!’.”
「可以舉個例子嗎?」
“The most typical case is a person who thinks he found a pattern in mark six. Such stupidity aside, the human brain is actually amazingly resilient to overtraining, but of course, when it fails, it causes disasters like the financial tsunami now.”
好!一言為定。於是,我們帶來首個給Scholar的Schoolala:
- How the financial system has targeted most people’s flaws in thinking that will cause a severe overtraining?
- How these thinking still actually persist in our society, or even university?
William has showed a little of his work and applied it to some events that everybody supposedly knows and feels interested in, “In some sense it extends from last workshop’s theme – Socrates believe that the wise is the one who knows what he doesn’t know – so that means he thinks the wise doesn’t “overtrain”! Ah, Socrates could make a good machine learning expert today!”
