Summary Below is the syllabus for the SPRING 2021 offering of the course. Fall 2021 will be similar, though the class will be offered in person only. INFO 2950 is an intro-level information science course on the foundations of data science. It covers topics including the standard Python data science stack, univariate and multivariate statistical analysis of small and medium-size datasets, regression methods, hypothesis testing, probability models, basic supervised and unsupervised machine learning, data visualization, and network analysis. Student who complete the course will be able to produce meaningful, data-driven analyses of real-world problems and will be prepared to begin more advanced work in data-intensive domains. Texts There is no required textbook for this class, though individual readings may be assigned throughout the semester. If you want additional information about course topics, we recommend the following books and resources: • General introduction to Python: John Guttag, Introduction to Computation and Programming in Python • General introduction to statistics: Allen B. Downey, Think Stats • Principles of data science: Joel Grus, Data Science from Scratch • Python data science stack: Jake VanderPlas, Python Data Science Handbook • Ethical issues in data science: Princeton Dialogues on AI and Ethics (case studies) Schedule Week 1 (beginning Monday, Feb 8) Intro and setup. HW 0 released. • Reading: If you aren't familiar with Jupyter notebooks and JupyterLab, review the JupyterLab documentation before section on Friday. • Monday (2/8): Intro • Wednesday (2/10): More intro, advice, notebooks, data types Week 2 (Feb 15) Dataframes and Pandas.

Course concludes (no final exam). Policies Harassment and respect All students are entitled to respect from course staff and from their fellow students. All staff are entitled to respect from students and from fellow staff members. Violations of this principle, whether large or small, will not be tolerated. Respect means that your ideas are taken seriously, that you feel welcome in class settings (including in study groups and online fora), and that you are treated as a full, co-equal member of the class. Harassment describes any action, intentional or otherwise, that abridges the respect owed to every member of the class. If you experience harassment in any form, or if you would like to discuss your experience in the class, please see me in office hours or contact me by email. The university also has reporting and counseling resources available, including those for sexual harassmentLinks to an external site. and for other bias incidentsLinks to an external site.. Academic integrity Each student in this course is expected to abide by the Cornell University Code of Academic IntegrityLinks to an external site.. Any work submitted by a student in this course for academic credit will be the student's own work unless specifically and explicitly permitted otherwise. Using other people's code is an important part of programming but, for group projects, the code should be substantially the work of the group members (except for standard libraries). Any code used in projects that was not written by the group members should be placed in separate files and clearly labeled with their source URLs.
