Description

With the ever increasing volume of data in the modern world, data visualization has become an essential component of every data analysis task. Visualization is an effective way to convey complex information and acts as a bridge between data and decisions.

This seminar will discuss the techniques and tools for creating efficient visualizations for the most important tasks related to large textual datasets.
The seminar is geared to be a series of highly interactive sessions with the students, seeking active classroom participations. The sessions will comprise of topic introductions, brainstorming for ideas, short group activities and active discussions. To maximize the practical learning, students will be expected to submit short practical assignments for the individual topics every week.
The second part of the seminar will consist of a project to be chosen by the student teams.
