學習動力與方向 (1/2)

關於學習和未來的方向,和一些同學們聊天,發現了一些有趣的現象。不論成績好壞許多人面臨的第一個問題是學習動機和動力,例如休學比率、課堂中必考」兩個字無動於衷。

學習動力與方向 (2/2)

如同如何準備研究所中所言,不一定要念研究所。在網路時代,知識的取得已經非常方便,例如 edX 或 Coursera,所以大學部的基礎知識自學的動力很重要 (1)。以 The Analytics Edge 而言,是 MIT 商業分析 (Business Analytics) 碩士的必修課,該碩士學費一年七萬美金,所以此線上免費課程價值一萬美金。

Software Engineering at Google

Titus Winters, Tom Manshreck, and Hyrum Wright, Software Engineering at Google, O'Reilly Media, March 2020. (Read online)

The Software Engineering at Google book (“SWE Book”) is not about programming, per se, but about the engineering practices utilized at Google to make their codebase sustainable and healthy. (These practices are paramount for common infrastructural code such as Abseil.)

Training One Million Machine Learning Models in Record Time with Ray

Eric Liang and Robert Nishihara, Training One Million Machine Learning Models in Record Time with Ray, Anyscale, December 17, 2022.

Ray and Anyscale are used by companies like Instacart to speed up machine learning training workloads (often demand forecasting) by 10x compared with tools like Celery, AWS Batch, SageMaker, Vertex AI, Dask, and more.

In this blog, we’ll cover:

  • Why companies are doing many model training
  • How to use Ray to train multiple models
  • The properties of Ray that enable efficient many model training

台灣軟體業的問題與成功策略

 葉肇元,為什麼台灣的軟體業不強?,2020/10/13

 台灣軟體業四個現象

1. 台灣市場對於軟體及服務定價過低,而且人才過度充沛。

2. 軟體的包裝跟行銷、以及授權談判都至為關鍵。

3. 講起台灣軟體創業成功的案例,真的是少得可憐,所以投資人興趣也不是很大。

4. 台灣政府對於推動軟體產業發展的政策好像還不是很夠力。

作業研究的持續改善

下學年要教我喜歡的作業研究。依照往例,再一次更新之前的版本

第一學期,考慮確定的環境和有限資源下,使用最佳化 (optimization),以最大化 (例如利潤) 或最小化目標  (例如成本)。第二學期,準備教不確定性環境下,如何分析、最佳化和做決策 (控制)。

2021 Tesla Impact Report

2021 Tesla Impact Report

Autopilot Safety

In 2021, we recorded 0.22 crashes for every million miles driven in which drivers were using Autopilot technology (Autosteer and active safety features). For drivers who were not using Autopilot technology (no Autosteer and active safety features), we recorded 0.77 crashes for every million miles driven. By comparison, NHTSA’s most recent data shows that in the United States there are 1.81 automobile crashes for every million miles driven.

螺絲廠產業智慧化轉型

蘇文彬,【5G專網工廠現場直擊】螺絲廠結合5G、大數據分析提高生產力、降低成本,加速產業智慧化轉型,iThome,2021-12-10

「一顆相同的螺絲,依照客戶訂單需求,不同的呎吋、處理方式,產生上萬種品項」,位於高雄的螺絲業者久陽精密總經理吳居諺一語道出螺絲產業現況。

在高雄梓官、橋頭、崗山一帶,為國內螺絲產業群聚地,臺灣將近有1,800多家螺絲業者,所生產的螺絲不只用於國內,也外銷至國外,從航太、醫療、電動車到3C電子,都有採用螺絲,臺灣更有「螺絲王國」之名,更是僅次於中國、德國,為全球第三大扣件出口國。

然而,螺絲產業卻面臨一些問題,由於客戶訂單需求的多樣化,導致螺絲生產少量多樣的現象,以久陽精密為例,該公司一年生產的螺絲品項就多達1萬3千種以上,每年產出約17億隻螺絲,在製造過程中,消耗約5萬件模具,使用7萬5千個船形物流桶。這樣複雜的生產過程中,過去大多是仰賴老師傅,以人工方式回報生產數據,再由專人登打輸入,但容易因為手寫錯誤,或是手動登打輸入數據也可能出錯。此外,傳產業的製造現場勞動人力還面臨逐漸老化,經驗不易傳承,人才斷層的危機。...

How Software Is Eating the Car

Robert N. Charette, How Software Is Eating the Car, IEEE Spectrum, 07 Jun 2021.

Ten years ago, only premium cars contained 100 microprocessor-based electronic control units (ECUs) networked throughout the body of a car, executing 100 million lines of code or more. Today, high-end cars like the BMW 7-series with advanced technology like advanced driver-assist systems (ADAS) may contain 150 ECUs or more, while pick-up trucks like Ford’s F-150 top 150 million lines of code. Even low-end vehicles are quickly approaching 100 ECUs and 100 million of lines of code as more features that were once considered luxury options, such as adaptive cruise control and automatic emergency braking, are becoming standard....

Boeing's 737 MAX: A Failure of Management, Not Just Technology

Michael A. Cusumano, Boeing's 737 MAX: A Failure of Management, Not Just Technology, Communications of the ACM, January 2021, Vol. 64, No. 1, Pages 22-25.

The congressional report had extensive access to company email and documents as well as detailed media coverage. These sources all describe the same decisions along with gradual but fundamental changes in Boeing's strategy and culture.

(高中) 數學與資訊工程

馬來西亞的學校提案,準備今年 5 月,開授相關線上演講,以便吸引高中生就讀資訊相關科系。去年12月中開校內協調會的時候,學校長官指派我,負責「數學與資訊工程 」。 月底到了,忙著提科技部計畫和撰寫研究的程式,但是,各種點子不斷地進入我的腦袋裡,只好趕緊把它寫下來,不然半夜進入我的夢鄉,擾人清夢。花了兩天,寫下初稿;最近又多次修正,前後花了不下 20 小時,決定提前定稿 ,以便改作其他教學和研究事務。

後來想一想, 既然這是一個有意義的工作,就準備把他錄成影片,並上傳 YouTube,以幫助有需要的年輕人。追求新知並傳授給學生,一直是我當老師快樂的泉源。

歡迎指正和提供寶貴意見。(pdf in 1) (pdf in 4,如果需要列印, 請雙面列印此版本,環保救地球)
