About Me Skills Certifications Projects Experience Education





Hello, I'm Wei Yang.

  • Ph.D. candidate in Mathematics and Statistics at Binghamton University, interested in Random Matrix Theory and Data Science.
  • Graduated from Baruch College, where the areas of study concentrated in Economics, Financial and Actuarial Mathematics.
  • Having more than 4 years of practical experience in the field of Machine Learning and Data Science.
  • Proficient in multiple scripting languages, including Python, R, Javascript and Julia.
  • I'm currently reading The Sensory Order by F. A. Hayek. A book on theoretical psychology from 1952 (as a point of reference, the Perceptron Algorithm is invented in 1958). It's surprising to see that Hayek's theory closely resembles our modern understanding of Neural Network Models.

  • I will be starting an internship in May at The AES Corporation, where I will be applying Machine Learning, Data Science and Random Matrix methods to projects in Renewable Energy and Commodity Trading.

  • Handwriting Recognition Web Application
    • Balanced an unbalanced image data set by generating randomly perturbed images from the existing ones, the resulted data set contains over 2,500,000 28 × 28 pixel images with 62 labels.
    • Trained a Convolutional Neural Network model with the generated data set in Python with TensorFlow, achieving 90% accuracy. The model is then exported as a JavaScript object, for web deployment.
    • Created a Handwriting Recognition Web Application with the trained model, and deployed to the project web page.
    • The deployed app can be found on the page Neural Networks 🔗.

  • S&P 500 Market Sectors Reclassification
    • Performed Web Scraping on Wikipedia and Yahoo Finance to extract the data of the S&P 500 companies over the last 10 years.
    • Cleaned, transformed the data, and denoised the transformed data using results from Random Matrix Theory.
    • Performed hierarchical clustering on the denoised data.
    • The Reclassification provides a better understanding of the market, and enabled additional options for portfolio optimization.
