I am a data scientist. This means that I like to use data to solve problems, whether through machine learning, statistical analysis or data visualization. Currently, I work as a technical lead at an artificial intelligence company in Silicon Valley that specializes in automating backend office works. I am also a professor at San Jose State University and Whitewater University of California and provide courses about artificial intelligence. My name is Andrew and I am 11 years old. I am interested in learning knowledge from each knowledge field and thinking about how to apply Invenrelation to create new knowledge at each field. I am Ray, and I was born in 2010. I like to invent new things and I help my brother Andrew and Father Shih-Yu Chang in preparing this great book: Knowledge Departments and Invenrelation.
