如何選填大學志願

緣起:朋友念南一中理組的兒子要念大學,詢問我的意見,所以才準備了此檔案的大綱 (電子檔)。

聽到我描述 (相關) 電子產品中需要的機構設計和熱流問題,覺得挺有趣的。後來,他選擇了成大機械系念完 6 年和尚學校的他,聯誼變成一個非常重要的考量因素。

歲月靜好

參加了數百次的系務會議,針對各種大大小小的提案和投票,每位老師都會拿到紙本說明,由主持人或系助理先朗讀條文內容,讓每位老師表達不同的看法和意見投票。有時候,遇到爭論不休的條文,一時之間老師們找不到共識,也不會強行表決;會議主席會裁決,再找時間討論。這就是民主的程序

也曾擔任兩年的校預算委員會委員,每學期開會十多次,都會邀請提案的單位前來說明。因為年度預算有限,頂多是刪減預算,從來沒有預算刪成負數

Statistical Modeling: The Two Cultures

Cynthia Rudin, Leo Breiman, the Rashomon Effect, and the Occam Dilemma, arXiv:2507.03884, 2025.

In the famous “Two Cultures” paper, Leo Breiman provided a visionary perspective on the cultures of “data models” (modeling with consideration of data generation) versus “algorithmic models” (vanilla machine learning models). I provide a modern perspective on these two approaches. One of Breiman’s key arguments against data models is what he called the “Rashomon Effect,” which is the existence of many different-but-equally-good models. The Rashomon Effect implies that data modelers would not be able to determine which model generated the data. Conversely, one of his core advantages in favor of data models is simplicity, as he claimed there exists an “Occam Dilemma,” i.e., an accuracy-simplicity tradeoff, where algorithmic models must be complex in order to be accurate. After 25 years of more powerful computers, it has become clear that this claim is not generally true, in that algorithmic models do not need to be complex to be accurate; however, there are nuances that help explain Breiman’s logic, specifically, that by “simple,” he appears to consider only linear models or unoptimized decision trees. Interestingly, the Rashomon Effect is a key tool in proving the nullification of the Occam Dilemma. To his credit though, Breiman did not have the benefit of modern computers, with which my observations are much easier to make.

「工業系 許某教授」和同學的「道歉」

Dcard: 6 月 27 日 14:25

奉勸各位工業系學弟妹 遠離許某教授(相信大家已經知道是誰了) 

成績不公開 課也不上叫大家看影片 (1)

影片的音質我還以為在聽什麼考古檔案  

更扯的是 有時候影片還沒拍到 自己花10分鐘在台上講不知道什麼鬼 就要大家寫心得出來 請問學生會通靈是不是 

能退選就退選 能停修就停修 免得影響那些想出國 推甄的好學生 

自己爛就算了 還要拖別人下水 什麼心態啊  

由衷希望系上可以把他調走 好不容易新進那麼多老師了

世界經濟論壇 2025 年未來就業報告

World Economic Forum, The Future of Jobs Report 2025,  7 January 2025.

Technological change, geoeconomic fragmentation, economic uncertainty, demographic shifts and the green transition – individually and in combination are among the major drivers expected to shape and transform the global labour market by 2030. The Future of Jobs Report 2025 brings together the perspective of over 1,000 leading global employers—collectively representing more than 14 million workers across 22 industry clusters and 55 economies from around the world—to examine how these macrotrends impact jobs and skills, and the workforce transformation strategies employers plan to embark on in response, across the 2025 to 2030 timeframe.

Reinforcement learning is enough to reach general AI

David Silver, Satinder Singh, Doina Precup, and Richard S. Sutton, Reward is enough, Artificial Intelligence, Volume 299, October 2021, 103535.

In this article we hypothesise that intelligence, and its associated abilities, can be understood as subserving the maximisation of reward. Accordingly, reward is enough to drive behaviour that exhibits abilities studied in natural and artificial intelligence, including knowledge, learning, perception, social intelligence, language, generalisation and imitation. This is in contrast to the view that specialised problem formulations are needed for each ability, based on other signals or objectives. Furthermore, we suggest that agents that learn through trial and error experience to maximise reward could learn behaviour that exhibits most if not all of these abilities, and therefore that powerful reinforcement learning agents could constitute a solution to artificial general intelligence.

張忠謀自傳 (下冊)

 張忠謀《張忠謀自傳》下冊 (1964-2018),天下,2024 

 「下冊」的第一篇「德儀篇」占全書三分之一篇幅,敘述我自 27 歲至 52 歲黃金年齡的崛起及衰退。德儀時期也是我最為熱情澎湃的年代。德儀讓我「獨上高樓,望盡天涯路」;為此,我無比地感激。但是,它對我的培植也激發了我要登上德儀顛峰的雄心。但是,這雄心是無法實現的;不說別的,只看 1970 年代美國德克薩斯州的客觀環境,就可斷定我的雄心很難很難實現。但是我的痴心,居然使我「明知不可為」的情況下,還在德儀多滯留了 5、6 年,後來連婚姻都賠上了。現在回想,那 5、6 年是多麼絕望的 5、6 年

Optimization in Fusion Energy

Raphael Rosen, The 10-Second Algorithm That Could Unlock Fusion Energy, Princeton Plasma Physics Laboratory, March 16, 2025.

QUADCOIL is a groundbreaking computer code that simplifies the design of stellarator magnets, ensuring plasma shapes remain practical for real-world construction.

Unlike traditional methods, it rapidly predicts magnet complexity, saving time and effort. By integrating engineering constraints early, QUADCOIL helps streamline the path to cost-effective fusion energy.
