Joshua Van Rossum

     Hello, my name is Joshua Van Rossum. I am a first year graduate student at the University of Illinois Urbana-Champaign, working towards my master's degree in Computer Science. I'm focusing my studies on machine learning and in my spare time, I have begun developing a site for NBA fans to create their own custom NBA statistics for ranking and comparing their favorite basketball players. To hone my data science and machine learning skills, I participate in online data science competitions through Kaggle. In my free time, I enjoy playing basketball and solving puzzles like sudokus, crosswords or Rubik's cubes.

Detecting Cancerous Masses in Mammograms

Senior Thesis Project

University of Wisconsin - La Crosse     La Crosse, WI

For my senior thesis project I trained CNNs and RNNs to identify mammogram images that contain cancerous masses using training data provided by the Mayo Clinic.

  • Designed and trained Convolutional Neural Networks (CNNs) and Recurrent Neural Networks (RNNs) using PyTorch Lightning to classify images with high accuracy
  • Split the dataset into training, validation, and test sets to ensure accurate model evaluation and prevent overfitting
  • Used image preprocessing techniques and transformations to build a robust training set and more accurate model
