CS 886: Deep Learning and Natural Language Processing
||DC 3355, x84659
Course time and location:||Mondays
3:00-5:50pm, DC 2585 (Starting from Jan 20) |
|Office hours:||I will try to do office
hours by phone (please call me at 519-500-3026 any time), or
|Reference Materials:||Papers listed below.
Deep learning has brought truly revolutionary changes in NLP research. This course intends
to review the recent progress of this exciting development.
The course will be run as follows.
I will do some lectures at the beginning introducing recent breakthrough results
that have fundamentally changed NLP research. These include word2vec, and pretraining models
such as GPT and BERT, and single headed attention RNN.
Then during the second part of the course,
each student will present one or a group of
research papers from the paper list I
give below (mainly from the first two lists, and please discuss with
me about your choices).
The paper you choose should represent an important progress in NLP
or on shortcomings of current approachs and how we can solve the
fundamental problem in NLP: understanding. Additionally, each student will need
to do one course project of your own choice and present
it to the class at the end of the term.
I expect the students already knew the basics of
deep learning such as different type of
gates, pooling, backpropogation gradient descent methods,
fully connected networks,
recurrent networks such as LSTM,
convolutional networks, and more specialized
structures such as residue networks and Grid LSTM, recursive structure,
memory networks, sequence-to-sequence structure, generative adversarial nets
(GANs). If you do not already know about these, you can read about
these materials online or go to my lecture notes at:
GPUs: In order for some of you to do experiments,
students can go to https://www.awseducate.com/application
to sign up. Amazon will review the application for a couple of days.
More information can be
found at: https://aws.amazon.com/cn/education/awseducate/
Sharcnet might be another resource for GPU.
It is possible to apply for a TPU from google,
Each student is evaluated according to the following three components:
Presentations and relevant papers will be posted on this website
(the presenters should provide these materials to me) several days before class.
[30 marks] Present a paper that represents one aspect of recent progress in NLP (30 minutes). You need to demonstrate thorough understanding of
the relevant literatures of your topic.
Presentations should be an in-depth
survey of the relevant literature and educational. Each week, we will have
three students presenting.
[65 marks] Do a project in one NLP direction, and present your own
project in class at the end of the term for 20 minutes. Hand in a
report of about 10 pages at the end of the term.
I will be very happy to discuss projects with you.
[5 marks] Class attendance and participation --
These marks will be given for free.
Course announcements and lecture notes will appear on this page.
Please look at this page regularly.
For presenting in class, please choose one (group) of the papers
in the following sites:
In principle, we want to hear about the most frontier results: (a) papers
related to BERT, GPT, Transformers, (b) 2018/2019 or newer papers. If you
wish to present something else, please discuss with me.

This Monday (Jan. 13)'s class is moved to Jan 17, 5pm, same
We will move to DC 2585, a larger classroom, starting from the Jan
20's class. The class time will be 3pm to 5:50pm, Mondays.
This way, all qualified students in the waiting list
will be able to enroll to this course.
For all those who would like to be added to this course,
please come to class today (Jan 20) and give me your student ID.
Announcement Jan 26, 2020. Attention: If you have visited a
city in China in the past 10 days, please wear a mask to attend the
class, to protect other students.
Announcement Feb. 3, 2020: If you had contact with
anybody who might have had contact with people with nCoV in the
past 15 days or if you have any
symptoms, please do not come to the class (and I do not need a doctor's
note). This class will no longer have
the attendance requirement. Everybody will have that 5% attendance
mark automatically. Of course, if you stay home, then please read
thru the presented materials on your own. You are expected to know
It's time to talk to me about your course (research) project. Note,
this is independent to your presentation (you can of course extend
the paper you have presented).
Please make sure you send me your presentation ppt or pdf file 1 day
before the presentation.
The final projects are due on April 10th, via emailing me in
pdf. (Please submit your 10 minute presentation together with the
The final project presentations will be on March 30 and April 1. 10
minutes each person. Please let me know which day you like to
present (first come first choose).
You will use your own laptop to
present. As the time will be very tight,
please test your computer connection beforehand.
Announcement March 13, 2020. Due to school corona virus closure,
We will stop the last day of
presentation for March 16. Please see the detailed arrangement below.
The 5 class attendance mark will now depend on your two
half-page reviews of two
presentations of final projects, respectively.
Announcement March 21, 2020. Course evaluation, attention all
Please go to Evaluation Website to
evaluate our course CS886 Section 002 (SEM), open
Sun. Mar 22 11:59 to Fri. Apr 3, 11:59pm. I wish you are all safe!
Announcement March 22, 2020. If any student have any question,
please call me any time at: 519-500-3026. Stay safe!
Announcement March 26, 2020. Deadlines postponed
The new deadline for submitting the final project report is
April 15 (any time in that day). On the same day, submit your voice-over-ppt (10 minute)
presenting your project. You no longer need to write reviews for
two other student presentations.
Announcement March 28, 2020. GPU's
Several students asked about GPU resources. There are 3 GPU
servers: gpu1, gpu2, and gpu3. First ssh to
datasci.cs.uwaterloo.ca, then using your linux.student.cs userid
and password. From there, ssh to one of the GPU servers. But I
think these are not sufficent to train big models like
BERT. Please use these only for light trainings.
Announcement April 11, 2020
April 15 is the deadline for submitting the project report
(approximately 10 pages) and voice-over-ppt (10 minutes).
All projects and voice-over-ppt will be posted on this website
unless you explicitly tell me not to do so with a good reason
(for example, the material will be published in a paper).
Announcement April 15, 2020
Today is the deadline. Please email me your project report and
voice-over-ppt. I will acknowledge each email.
For submission: please send email attaching 2 files, if possible. Do not do
anything else such , as zip etc, to make things easier on my
Announcement April 16, 2020 As many people do not wish
to publicize their work because they wish to continue their work
as a part of larger research programs, I decide we will not
publish anybody's ppt and final project.
Announcement April 26, 2020 This is our last
announcement of the class. I have now finished marking
all the reports and watched all presentations. I will input these marks to the university
I would like to take this chance to thank every student in this
COVID-19 stopped me from saying good-bye to you, I wish all of
you stay healthy and carry on to do great research in NLP and
Please start picking topics/papers. Then I will put the topics or
papers behind each name. For each topic/paper, we will have only
one student presenting. Therefore, it is a good idea pick up
topics you like early.

project presentations. We will not do face-to-face in class
presentations. Each student will still be required to
prepare a 10 minute voice-over PPT (see
create voice-over for PPT presenttion)
for your project (in addition to your
course project paper), making sure that they
are understandable for other people to read.
All of you will email your project 10-minute ppt to me on April 15
