Fixed point and optimization methods for machine learning with applications to data prediction and classifiaction

• Motivation
  • The applications
    • ChatGPT
    • Stock market (more info from AI)
    • autonomous vehicles
    • medical uses/ health care
  • Intuitive behind Neural Network (NN)
    • hidden layer
    • simple NN (SLFN)
    • deep learning NN
  • Goal of data analysis
    • find insights
    • predictions and classification
• Extreme learning machine
  • the word "extreme" is for "very fast"
  • weight and bias are chosen ramdomly
  • minimize $||\mathbf{H}\eta -T|{|}_2^2+\lambda ||\eta |{|}_1$
  • find $\eta$ by fixed pt. methods and (convex) opt. methods
• Fixed point method for ML
  • find fixed pt. :$$x^{\ast }={\text{prox}}_{\alpha g}(I-\alpha \mathrm{\nabla }f)(x^{\ast }),$$where $\alpha >0$
  • subdiff.
  • forward-backward algo. (interations)
• Opt. method for ML
  • line search tech.
  • Convex Bilevel opt.
• App. in data prediction and classification
  • https://feveroliang.pythonanywhere.com
• New innovation for Big data prediction

Physics

11:15 - 11:50
Prof. Chi Yen Huang, National Changhua University of Education

Contact-free homogeneneous liquid crystal (LC) alignment realized using doping of organic rubrene molecules

• Introduction
  • Applications
    • OLEDs
    • OFETs
    • unif. LC alignment
    • LC lens(focus photo, clear image)
  • a kind of meterial, align in order
  • orientaiton is crucial
  • Goal: control the orientation
  • rubbing treatment
    • dust
    • surface damage
    • elec. charge
    • need contact-free method
  • photo alignment
  • polymer stabilization
  • self assemble monolayer
  • (2D) single crystal graphene (SCG)
• Motivation
  • weakly conductive layer (WCL)
  • SCR can act as WCL
  • can replace the rubbed method
• Method
  • p-type organic semiconductor
  • $\pi -\pi$ electron stacking
  • XRD measurement
• Result
  • alignment is determined by 當初填入的方向
  • lower operation voltage
  • excellent stability
• Extension
  • variable pretilt angle
  • determine the angle not only by filling direction
• Conclusions

Chemistry

13:30 - 14:05
Prof. Balaji R. Jagirdar, Indian Institute of Science

Tandem hetrogeneous catalysis for reversible hydrogen storage in liquid organic hydrogen carriers

• need clean power
• Hydrogen: good power

Biology

14:05 - 14:40
Prof. Mohamed Hatha Abdulla, Cochin University of Science and Technology

Role of Arctic Tern in the dissemination of antibiotic resistant bacteria during inter-hemisphere migration

Earth and Environmental Sciences

14:40 - 15:15
Prof. Chris Clark, Curtin University

Advances in integrating petrochronological and geodynamic models of high-grade matamorphic systems

Poster Session

15:30 - 17:40

收集到了三張海報！(不確定作者是否希望海報被放到網路上，故不放照片)

3. Impact of Geographical and Climatic Factors on Melioidosis Hotspots in Southern Taiwan
   Authors: Kuang-Yueh Chen¹, Sung-Po Chao¹, Chien-Cheng Chen², Chung-Yuan Ren^{1
   1} Department of Physics, National Kaohsiung Normal University
   ² Department of Biotechnology, National Kaohsiung Normal University

真心佩服海報講者們
老實說因為太怕生了，所以每去看一張海報、問作者問題、交流，我會先花n分鐘作好心理準備，然後交流完再躲到廁所裡回復體力後，再去看下一張XD
所以更別說海報講者兩小時內要面對所有來找他們問問題的人，真的都很厲害！

Welcome Party

18:00 - 20:00
University 1st Cafeteria

看它佈置成這樣 用意應該是讓大家social?

好看又好吃的食物

不怎麼喝酒，不過開場環節是甘杯，而且真的很香，所以還是喝了一點
有新瀉大學的學生來我們這桌，就鼓起勇氣和他說這邊的酒和食物和校園都很棒
(我知道這個開場白很爛 但我真的不會social QAQ我努力了)
