Hi, I'm Junwen Pan.
I'm a computer vision researcher at ByteDance. My research interest includes weakly/semi-supervised image segmentation, vision-language learning, and explainable machine learning. Currently, I am working on VQA grounding.
I enjoy developing tools that help us live happier and more productive lives. My open-source code involves Python, JavaScript, Java, and C♯ programming languages.
