WEBSC Workshop 1: Introduction to Topic Modelling

Western Epi Bio Student Council's (WEBSC) first Workshop of its August Workshop Series hosted by Jacqueline Kueper, PhD Candidate in Epidemiology and Computer Science.

Topic modelling is an unsupervised machine learning technique used to identify patterns of co-occurrences in data. For example, to identify clusters of words (topics) that characterize a set of documents or open-text survey responses.

The first part of this session will introduce core concepts, methods (with a focus on non-negative matrix factorization), and example use cases. The second part will include hands-on examples in R. To fully engage and follow-along, introductory knowledge of R is needed. Base code and public data will be provided/linked; however, you may bring your own dataset to experiment with during the demos.

All funds from the Workshop series goes towards WEBSC initiatives in the Department of Epidemiology and Biostatistics, including the Student Travel Award.

Zoom Meeting Link will emailed to all attendees the night before and a couple hours prior to the start of the workshop.

Please contact Shreni Patel (spate743@uwo.ca) or Maliha Mamun (mmamun7@uwo.ca) for any questions.

We look forward to seeing you there!
