在台一度「學到怕」的程式語言，在史丹佛只求「會開機」的課堂上學會了！

賴冠穎，在台一度「學到怕」的程式語言，在史丹佛只求「會開機」的課堂上學會了！現在他把方法帶回台灣，換日線，2021/11/12

在畢業門檻的 15 門課裡，扣除 10 門材料系上的課程之外，學生還必須要再跨系選修 5 門課。在學長的強烈建議下，他修了「CS106A 程式設計方法論」（Programming methodology），當時這門課的修課條件僅標註著「會開機就行」，讓原本對程式語言信心全失的 Jerry 決定再給自己一次機會。想不到這門課，也讓他對自己的職涯靈感「正式開機」！

書 Matching Supply with Demand

G. Cachon and C. Terwiesch, Matching Supply with Demand: An Introduction to Operations Management, 1st Edition, McGraw-Hill, 2006. (有第四版)

本書是作者針對 Wharton 企管碩士 (MBA) 核心課程 Operations Management (作業管理) 所發展出來的課本。

根據實際的公司和數據，透過清楚和基礎的數學分析，並融入最新的研究結果，呈現出一本讓人眼睛一亮的好書。

兩位作者的論文被高度引用，說明名校的教授能夠創造知識，也努力地將之轉成教材，教學與研究並進。

A unified framework for stochastic optimization

W.B. Powell, A unified framework for stochastic optimization, European Journal of Operational Research, 2019, Volume 275, Issue 3, 16 June 2019, Pages 795-821. (pdf)

Stochastic optimization is an umbrella term that includes over a dozen fragmented communities, using a patchwork of sometimes overlapping notational systems with algorithmic strategies that are suited to specific classes of problems. This paper reviews the canonical models of these communities, and proposes a universal modeling framework that encompasses all of these competing approaches. At the heart is an objective function that optimizes over policies that is standard in some approaches, but foreign to others. We then identify four meta-classes of policies that encompasses all of the approaches that we have identified in the research literature or industry practice. In the process, we observe that any adaptive learning algorithm, whether it is derivative-based or derivative-free, is a form of policy that can be tuned to optimize either the cumulative reward (similar to multi-armed bandit problems) or final reward (as is used in ranking and selection or stochastic search). We argue that the principles of bandit problems, long a niche community, should become a core dimension of mainstream stochastic optimization.

「全球品牌都會變綠，遲早而已，」歐萊德董事長葛望平說。
歐萊德是台灣企業中，很早就喊出在一定時間內，承諾達成百分之百再生能源的企業；過去幾年，他們不僅研發出百分之百再生塑膠材料（PCR，Post-Consumer Recycled）製成的洗髮精瓶身、全球第一支再生壓頭，2020年全品項也達成碳中和成果。...

47-779 Quantum Integer Programming

Prof. Sridhar Tayur, Dr. Davide Venturelli, and David Bernal, 47-779 Quantum Integer Programming (QuIP), Fall 2020. (lecture note)

This course is primarily designed for graduate students (and advanced undergraduates) across CMU campuses interested in integer programming (with non-linear objective functions) and the potential of near-term quantum computing for solving combinatorial optimization problems. By the end of the semester, someone enrolled in this course should be able to:
Identify the current status of quantum computing and its potential uses for integer programming
Access and use quantum computing resources (such as DWave Quantum Annealers)
Set up a given integer program to be solved with quantum computing
Work in groups collaboratively on a state-of-the-art project regarding applications of quantum computing and integer programming

用AI改善機關作業效率，法務部靠IT再造為轉型打底

蘇文彬，用AI改善機關作業效率，法務部靠IT再造為轉型打底，iThome，2021-10-28

今年2月，法務部旗下各檢察機關有了一套新的語音辨識系統，透過中文語音辨識技術，不只可以快速產生一般會議的文字紀錄，甚至成為檢察機關偵辦案件的幫手，將蒐集各式影音證據，利用語音辨識快速產生逐字稿，讓檢察官能夠快速勘驗案件相關證據，不需再聽完完整的語音資料，快速找到可能的線索。
法務部這套語音辨識系統背後使用AI Labs的雅婷逐字稿語音辨識技術，只用了大量了會議錄音檔來訓練，而為了讓系統能夠辨識專業的司法用語，還搭配司法用語詞彙，供業者不斷調校AI模型，目前可以進行純國語的辨識，辨識率也達到法務部設定目標。
近幾年大力推動AI應用的法務部資訊處長鄭輝彬表示，內部測試結果，辨識準確率能達到9成以上，除了法務部與檢察機關，明年計畫也將讓行政執行、矯正機關試用。...
