    Recommendation System on Netflix Users data Dec. 2019
    • Implemented Min-Hashing algorithm and Local Sensitive Hashing model (LSH) model to find similar users measured by Jaccard similarity
    • Improved 14% accuracy by tuning the LSH to minimize the false negative and the false positive
    Floor Plans Generation by Generative Adversarial Network (GAN) Nov. 2019
    • Processed the floor plan images data by resizing, boundary detection, etc using OpenCV in Python

    Floor Plans Generation by Generative Adversarial Network (GAN) Nov. 2019
    • Processed the floor plan images data by resizing, boundary detection, etc using OpenCV in Python
    • Trained and fine-tuned pix2pixHD models (a state-of-the-art conditional GAN model) from scratch to turn floor boundary images into synthesizing floor plans in PyTorch
    Topic Modeling and Author Prediction by Natural Language Processing (NLP) Sept. 2019
    • Built a Gradient Boosting Tree to predict the authors of documents by NLP (lemmatization and TF-IDF)
    • Trained a Latent Dirichlet Allocation (LDA) model to identify topics for each author
