This document outlines a course on data design and creative research practices. The course covers topics like data mining, visualization, analysis techniques, and prototyping. It discusses methods for gathering meaningful data through surveys, crawling, and user experience design. Example analysis techniques covered include clustering, classification, regression, and association rules. Students are asked to consider what types of systems or products could be built by analyzing collective intelligence data related to topics like politics, entertainment, food, and more. For a homework assignment, students form groups to explore potential data sources and analysis techniques for a collective intelligence topic.

- 25. Homework: Data Mining 1. Form groups! 2. Choose a Collective Intelligence topic from Lecture 1, or propose similar. 3. Make a list of data sources that might provide insights to that topic. 4. Propose a set of meaningful questions about the data based on your intuition. 5. How would you have to clean/process your data to start answering those questions? 6. Consider clustering, association rules, anomaly detection, classification. For each technique, how might you apply it to the data and what would it show? 7. Document your work and be prepared to present. HTTP://WWW.FLICKR.COM/PHOTOS/31907740@N00/4860840019/
