This is a site for my homeworks in SI618 class: Exploratory Data Analysis. The formal description of the class is:

Aims to help students get started with their own data acquisition and analysis. Data analysis is crucial to evaluating and designing solutions and applications as well as to understanding information needs and use. Students in this course (who will have just completed SI 601: "Data Manipulation") will learn techniques of exploratory data analysis using scripting, text parsing, structured query language, regular expressions, graphing, and clustering methods to explore data. Students will be able to make sense of and see patterns in otherwise intractable quantities of data.
