Principles and Application of Data Science
Min-hwan Oh, Seunggeun Lee, Jaejin Lee, Hyung-Sin Kim, Sang Kyun Cha, Hyunwoo Park, Sanghack Lee, Joonseok Lee
Goals
Combining computing, machine learning algorithms, and inferential thinking based on probability/statistics, data science provides a new paradigm for deriving insights and new knowledge from data and solving real-world problems. The purpose of this course is to introduce core principles and techniques of data science such as basic theoretical knowledge and analytical skills necessary for students of various majors to solve data-driven problems. In addition, students will learn data-centric thinking and decision-making based on data.
