β Week 09 - Checklist
DS202 - Data Science for Social Scientists
Comprehension Check
By the end of the week, you should be able to:
- Explain the difference between supervised vs unsupervised learning
- Explain how K-Means works
- Run K-means clustering on a dataset
- Produce an βelbow plotβ, and explain how some people use it to justify the choice of the number of clusters for k-means
Time Management Tips
Here is a suggestion of how to program your week in relation to this course:
If your lab is on Monday
If your lab is on Monday:
On Monday:
π₯ Download: Before or once you arrive at the classroom, download the DS202_2022MT_w09_lab_rmark.Rmd file that contains the lab roadmap (under ποΈ Week 09 section on Moodle). Or browse the webpage version here.
π» Participate: Actively engage with the material in the lab. Ask your class teacher for help if anything is unclear. Work with others whenever possible and take notes of theoretical concepts or practical coding skill you might want to revisit later in the week.
π Read: Find some time to read (James et al. 2021, sec. 12.4.1) and reinforce your theoretical understanding of K-Means Clustering; it is a very short section.
- As you go through the text, try to connect what you read to the things you heard about in the W05 lecture or the examples you explored in the lab.
Tuesday to Thursday
βοΈ Solve: the Summative Problem Set 02.
The deadline is Tuesday, 29 November 2022, 11:59 PM but better not to leave it to the last minute!
If you finish sooner, you will have more time to ask questions and you will have more βmental bandwidthβ to learn about text mining applications later this week.
π Study group: Talk to your colleagues on Slack or whatsapp and try to join or organize a study group to work on the summative problem set together.
Friday
π« Attend the lecture: This week, Prof. Ken Benoit is confirmed to come and deliver a talk Applications: Text as Data & Topic Modelling.
π Solve the take-home exercises: There are four take-home exercises in the W09 lab.
Any time
π You know the drill. Share your questions on the
