Data science framework for TFT-LCD manufacturing

Chia-Yen Lee and Tsung-Lun Tsai, Data science framework for variable selection, metrology prediction, and process control in TFT-LCD manufacturing, Robotics and Computer Integrated Manufacturing 55 (2019) 76–87.

TFT-LCD panel manufacturers rely on experimental design and engineering experience for process monitoring and quality control throughout the production line. To shorten production and reduce the cost of labor resources, this study proposes a three-phase data science framework embedded with several data mining and machine learning techniques, which can identify the variables affecting yield, predict the metrology result of photo spacer process, and suggest the process control in the color filter manufacturing process. An empirical study of Taiwan's leading TFT-LCD manufacturer is conducted to validate the proposed framework. The results indicate that the proposed framework effectively and quickly selects the important variables, predicts the metrology result with higher performance, and identifies the main effect and interaction effect of the selected variables for yield improvement.

TutorABC 用 AI 幫你挑學伴

謝明彧，線上教育獨角獸TutorABC 楊正大用AI幫你挑學伴，遠見雜誌，2018-11-29

一開始，楊正大就明白自己不是要開補習班，而是「個性化的網路教學平台」，原本以實體為主、數位為輔，但2003年的SARS事件，學員大量轉移到線上，不少使用者發現「原來數位比實體更好用！」楊正大看見「數位教育」發展潛力，2004年成立TutorABC，全力進攻線上。

2006年是轉捩點。楊正大以數據為基礎、AI為核心，開發出的「動態課程系統DCGS （Dynamic Course Generation System）」，能精準配對學生、老師與教材，獲得專利。

這個結合大數據和演算法的人工智慧系統，快速比對學生需求、老師背景、教材內容，以及學員的人格特質，達成「讓任何人在想要的時間，找到喜歡的老師，搭配合適的同學，上需要的教材內容」，「個性化教育，從此變可能！」楊正大回憶。...

Advanced programming languages like Python and domain-specific languages like TensorFlow have dramatically improved programmer productivity by increasing software reuse and by raising the level of abstraction.
