About Me Skills Experience Certifications Education





Hello, I'm Wei Yang 杨炜.

  • Data Scientist at The AES Corporation, leading the Renewable Generation Forecasting platform, supporting LNG Optimization, Turbine Fault Detection, LLM-based resume evaluation, and EVSE planning. Recommendations from peer and direct manager can be found on my LinkedIn profile 📩.

  • A self-proclaimed photographer. I love capturing pictures of architecture, landscapes, stars, and wildlife. These photos not only showcase the world but also reflect a part of myself at that moment. I've set foot on six continents, with Antarctica being the only one left to explore.

  • Taught various courses in Mathematics and Statistics while doing Ph.D at Binghamton University. My notes for Linear Algebra, Calculus 3 and Statistics, can be found at the following links : 🔖(LinAlg), 🔖(Cal3) and 🔖(Stat).
  • Studied Mathematics and Statistics, researched in Random Matrix Theory at Binghamton University.
  • Studied Economics and Mathematics, with a focus on Financial, Actuarial and Computational Mathematics at Baruch College.

  • Skilled in multiple scripting languages, including Python, R, Javascript and Julia.

  • On this website, I will be creating notes on various materials for myself and others to learn or review.

    The AES Corporation - Digital Solutions and Innovation Data Scientist
    May 2023 -- Present, Houston TX
    • Wind & Solar Generation Forecasting
      • Spearheaded development of the AES Farseer renewable generation forecasting system for 30+ AES wind and solar sites across the Americas. Achieved 30.4% mean absolute error reduction compared to vendor models, generating $12.2M in operational savings by improving forecast accuracy.
      • Researched the impact of extreme weather events such as icing on wind generation, calibrated models to the local weather patterns, and achieved a 45% reduction in forecast error under extreme weathers.
      • Enhanced model interpretability and strengthened stakeholder trust through the use of explainable AI (XAI) techniques.
    • Solar Panel Dust Detection & Fault Detection System
      • Implemented EfficientNet architecture in PyTorch for solar panel dust detection, achieving a 16% improvement over traditional CNN models.
      • Developed turbine fault detection models using Moving Window PCA, reducing fault detection time from 7 days to under 48 hours. The models reduced maintenance costs by over 45%.
    • LNG Optimization Model
      • Created stochastic dual dynamic programming (SDDP) models in Python/OR-Tools to optimize LNG procurement strategy, increasing profit by 24% through dynamically balancing inventory, obligations, and price volatility.
    • Other Projects
      • Collaborated with HR specialists on resume scoring models using Large Language Models (LLMs) & Natural Language Processing (NLP) techniques. The model reduced the resume screening time of 300 applications from 2 weeks to 1 day.
