Foundations of Data Science (데이터사이언스 원론)
Summer 2021
Monday to Friday, 09:30 - 10:45 am (Lecture), 11:00 - 11:50 am (Lab)
Summary
This course aims to cultivate theoretical knowledge and hands-on experience necessary for students from various backgrounds to deal with and analyze big data. Through this course, students learn the basic knowledge of data-oriented computing, quantitative thinking and reasoning, and exploratory data analysis. Based on this, students learn key principles and techniques for data-driven problem solving, such as data analysis methods, big data management systems, problem formulation, data collection and organization, visualization, reasoning, predictive modeling, and decision making.
