美國商學院強大的原因
張忠謀在清華大學的演講提到了「台灣理工科與美國相差不大,但商學院卻比美國差很多」。就某方面來說,台灣的商學院其實不算太差,但是跟台灣的理工學院在國際間的等級相比,商學院真的很差。或許我們應該要先問的是,商學院是什麼?...

中國無人計程車便宜效率高
施慧中 / 編譯,中國無人計程車便宜效率高 衝擊傳統駕駛就業市場,公視,2024-08-23
人工智慧時代,無人計程車成為時代趨勢。中國百度旗下的「蘿蔔快跑」是先驅者,在武漢有500多輛規模,超便宜價格戰,讓傳統計程車駕駛面臨飯碗不保的壓力。專家指出AI全面取代人類駕駛,還有至少5到10年,但科技與就業之間的衝突仍須及早應對。

翻轉教室 (Flipped classroom)
方式:
- 上課前看完影片,做筆記,總結重點。看一下相關的習題,想一下在哪一節,如何做?
- 只寫標題不是總結重點,例如報童模型、隨機過程、決策準則、轉移機率。
- 好的例子
- 空間分佈等候線:服務時間不是指數函數分配,且有上下限。
- 動態規劃:由終點往起點計算 (Backward in time) 動態;當存貨水平不同,價格會變化。針對每周、所有存貨水平、先前價格...所以動態規劃在這裡可以得出最佳解。
- 流量平衡方程式:進一定會等於出。三種形式。所有的機率和一定等於一。

Future of Decentralization, AI, and Computing Summit
The Future of Decentralization, AI, and Computing Summit, hosted by Berkeley RDI, aims to bring together researchers, innovators, thought leaders, and builders to showcase and discuss the future of decentralization, AI, and computing.
In particular, the event will include topics on how AI/ML and decentralization technology can help each other, and how to build a full decentralized, open source stack for AI/ML, including 1) decentralized ML infra such as decentralized training, inference, provenance, integrity guarantees, 2) open source data, model, and tooling, 3) personalized AI with privacy and trustworthiness; 4) democratic and decentralized process for AI governance and alignment. We hope this summit will provide an opportunity for researchers from diverse backgrounds including AI/ML, Security & Privacy, game theory, economics, decentralization technology, to get together and cross pollinate to help seed the initial discussions in this important space and make advancement in responsible AI with decentralization.

文中指出,從 1997 年擊敗西洋棋人類冠軍的「深藍」,到 2023 年爆火的 ChatGPT,再過 15 年,人工智慧已經發展到可以「合成知識」(synthesize knowledge) 的地步,可以創作詩歌、創作藝術品、診斷疾病、編寫總結報告和電腦程式碼,甚至可以設計與人類製造的積體電路相媲美的積體電路。

學習數學的四個層次:(3) 在許多行業的應用
2015/12/1 初稿,持續更新中。
一般性說明
- 數學是科學之母,科學則是工業的基礎,所以大學工學院的數理化課程總學分超過 1/3。可以參考如何選填大學志願。
- 應用在不同的領域 (理工商醫農、教育),如財務工程、設計電腦、貨物產銷、工程師、使用統計學分析學習成效等等。
- 抽象的模式與思考的方式,適用於現在與未來的應用,以微分為例,物理學的距離微分是速度,經濟學中成本的微分是邊際成本,電子學的電荷微分是電流。也就是說,可以使用函數表示任何待解的問題,函數的微分便可以研究其變化和極值的情況,例如機器學習中,超參數 (hyperparameter) 的學習 。
- 基本的原則變動不大,微積分、機率和統計學、和線性代數已經有 200 年以上的歷史,可幫助未來的自我學習。許多人說學校學的東西,畢業後立即過時或沒用,我覺得很疑惑。大學只是基礎教育,必須不斷地學習新的東西,以因應產業和職務的變化;最近熱門的大數據 (big data) 和人工智慧 (artificial intelligence),其數學基礎正是這些課程
。
