Me working on "CS276: Information Retrieval and Web Search"

CS276

My reading notes for CS276: Information Retrieval and Web Search, Spring 2019 from Stanford University.

Mostly contains the summary of the chapters from Introduction to Information Retrieval, along with memos for certain lecture slides and other sources.

Note: To cope with mathematical notations, I've used Pandoc to convert all the Markdown notes into LaTeX pdfs. I think this is the easiest solution at the moment to view math formulas on GitHub. Please let me know if you think there's a better solution.
