Hi there, Iām Andy Zhang. A data scientist, machine learning engineer, and open-source community advocate.
- I was engaged in research related to machine learning (sparse PCA/tensor decomposition, stagewise algorithms etc.).
- I specialize in the statistical modeling and development of machine learning software.
- I enjoy experimenting CV/NLP projects with cutting-edge deep learning models using PyTorch.
- I've been actively engaged in projects centered around RecSys/LLMs/RAG.
- I am currently seeking job opportunities in the fields of data science and machine learning.
