Graphical Models for Primarily Unsupervised Sequence Labeling (link)
ABSTRACT: Most models used in natural language processing must be trained on large corpora of labeled text. This tutorial explores a "primarily unsupervised" approach (based on graphical models) that augments a corpus of unlabeled text with some form of prior domain knowledge, but does not require any fully labeled examples. We survey probabilistic graphical models for (supervised) classification and sequence labeling and then present the prototype-driven approach of Haghighi and Klein (2006) to sequence labeling in detail, including a discussion of the theory and implementation of both conditional random fields and prototype learning. We show experimental results for English part of speech tagging.
Notes on Types and Programming Languages (PDF)
A (highly) compressed coverage of the topics in Types and Programming Languages by Benjamin Pierce. Includes material on type systems and functional languages as well as fundamentals of the lambda calculus. Covers Chapters 1-12.
MySQL is a useful database server, but sometimes I forget the syntax of some commands that I use a little less often, so I decided to make myself a cheat sheet of common commands.
This is a popular introduction to Unix document I wrote a while ago. Sections include Why Unix?; What's Darwin?; Basics of Darwin; Introduction to shells; Running system commands; Basic shell customization (see my article below for more info on customizing tcsh/zsh); Permissions; Running programs; What's NetInfo?; Basics of compiling; Process management; Introduction to text editors (thorough explanation of pico, vi, and emacs); and Introduction to X Windows. Currently at version 2.1.2. Warning: though some people continue to find this useful, note that this was written almost 10 years ago, and refers to early versions of Mac OS X; several of the comments in the document may no longer be valid.
This is a tutorial on how to customize your tcsh or zsh shell prompt using funky formatting sequences and colors.
