# Schedule

This schedule is provisional and will change as the semester progresses. Readings that are not linked here are available on the Piazza site. (I initially put some up on the Moodle site but some people had problems accessing them there.)

Keynote’09 versions of slides are available by changing “.pdf” to" “.key” in the url.

1 Tue 9/2 Introduction [slides]

Optional reading: J&M Intro, ch 1

2 Thu 9/4 Word Counting, Probability Review

Exercise1 due
3 Tue 9/9 Language Models [slides] [extra notes]; next lecture has a few slides too

For PS1: You need to download [ps1.ipynb], load it in ipython notebook, record your work there, and submit your finished .ipynb file. For viewing convenience only, here is an HTML version of the file: [ps1.html]. See also IPython install notes.

PS1 out: [ps1.ipynb], [ps1.html]
4 Thu 9/11 Machine Translation (Model 1 and EM)

Readings. In this course we only cover Model 1 with technical depth, and only cover the high level aspects of the other IBM models.

5 Tue 9/16 Machine Translation [slides]

Exercise3 due
6 Thu 9/18 Classification: Naïve Bayes [slides]

Reading: J&M 3rd ed draft, ch 6 (here).

Optional: to better understand the relationship between Naïve Bayes and logistic regression, see Mitchell’s draft chapter here

PS1 due (Friday 11:59pm)
7 Tue 9/23 Classification: Logistic Regression [slides]

J&M 3ed ch6 covers this, but these notes/tutorials on logreg, linear classifiers, and log-linear models may also be helpful:

• Hastie ESL book, chapter 4, especially 4.4-4.5. (free online). Covers binary logistic regression especially well.
• Collins notes on log-linear classifiers. (no exercises). Uses the log-linear notation, which we will prefer to use for multiclass outputs.
• Murphy MLPP book, chapter 8. Exercises 8.6, 8.7 are nice.
• Eisenstein GTNLP notes, chapter 5, especially 5.4-5.6. (no exercises).
• Videos: Ng’s Coursera lectures, week 3, on binary logistic regression.
Wed 9/24

Tue 10/14

No class (Monday schedule day)

Midterm review session: 5:30-7pm, CS 142

Thu 10/16

In-class midterm [midterm topics/questions]; partial solutions on piazza

The midterm will consist of short answer and multiple choice questions. It may include any topics covered so far in class, or in the readings. In a few cases, I’ve added notes on the schedule next to readings, explaining which elements of them you do not have understand in some cases. The midterm may include some limited mathematical derivations, but no full-blown proofs.

The midterm is closed-book. But if you like, you may bring a cheatsheet: a single sheet of paper of whatever notes you want to have for the test. (Front and back … use standard sized paper, please, like letter or a4.)
