The following is a collection of tutorials, lecture notes, and topical notes covering subjects such as mathematics, topological data analysis, image processing, and machine/deep learning. These mathematical lecture notes and materials were written by me and include complete lecture series or seminars, as well as specialized notes focusing on exercises in specific subjects (e.g., sheaf theory, algebraic geometry, algebraic topology). Many of these notes originated from student seminars, teaching assistant courses during my Master's studies at National Taiwan University, PhD studies at National Taiwan Normal University, and group seminars conducted at Nanyang Technological University and the National Central University.
