The Course Project is an opportunity for you to apply what you have learned in class to a
problem of your interest. Potential projects usually fall into these two tracks:
If you're coming to the class with a specific background and interests (e.g. biology,
engineering, physics), we'd love to see you apply ConvNets to problems related to your
particular domain of interest. Pick a real-world problem and apply ConvNets to solve it.
You can build a new model (algorithm) with ConvNets, or a new variant of existing models,
and apply it to tackle vision tasks. This track might be more challenging, and sometimes
leads to a piece of publishable work.
One restriction to note is that this is a Computer Vision class, so your project should
involve pixels of visual data in some form somewhere. E.g. a pure NLP project is not a good
choice, even if your approach involves ConvNets.
To get a better feeling for what we expect from CS231n projects, we encourage you to take a
look at the project reports from previous years:
For applications, this type of projects would involve careful data preparation, an appropriate
loss function, details of training and cross-validation and good test set evaluations and model
comparisons. Don't be afraid to think outside of the box. Some successful examples can be found
For models, ConvNets have been successfully used in a variety of computer vision tasks. This
type of projects would involve understanding the state-of-the-art vision models, and building
new models or improving existing models for a vision task. The list below presents some papers
on recent advances of ConvNets in the computer vision community.
You can work in teams of up to 3 people. We do expect that projects done with
3 people have more impressive writeup and results than projects done with 2 people. To get a
sense for the scope and expectations for 2-people projects, have a look at project reports from
You may consult any papers, books, online references, or publicly available implementations for
ideas and code that you may want to incorporate into your strategy or algorithm, so long as you
clearly cite your sources in your code and your writeup. However, under no circumstances may you
look at another group’s code or incorporate their code into your project.
If you are combining your course project with the project from another class, you must receive
permission from the instructors, and clearly explain in the Proposal, Milestone, and Final Report
the exact portion of the project that is being counted for CS 231n. In this case you must prepare
separate reports for each course, and submit your final report for the other course as well.
The project proposal should be one paragraph (200-400 words). Your project proposal should
What is the problem that you will be investigating? Why is it interesting?
What reading will you examine to provide context and background?
What data will you use? If you are collecting new data, how will you do it?
What method or algorithm are you proposing? If there are existing implementations, will you
use them and how? How do you plan to improve or modify such implementations? You don't have
to have an exact answer at this point, but you should have a general sense of how you will
approach the problem you are working on.
How will you evaluate your results? Qualitatively, what kind of results do you expect (e.g.
plots or figures)? Quantitatively, what kind of analysis will you use to evaluate and/or
compare your results (e.g. what performance metrics or statistical tests)?
Please submit your proposal as a PDF on Gradescope. Only one person on your team should submit.
Please have this person add the rest of your team as collaborators as a "Group Submission".
Fine-grained requirements are listed on Piazza.
Your project milestone report should be between 2 - 3 pages using the
The following is a suggested structure for your report:
Introduction: this section introduces your problem, and the overall plan for approaching your problem
Problem statement: Describe your problem precisely specifying the dataset to be used, expected results and evaluation
Technical Approach: Describe the methods you intend to apply to solve the given problem
Intermediate/Preliminary Results: State and evaluate your results upto the milestone
Please submit your milestone as a PDF on Gradescope. Only one person on your team should submit.
Please have this person add the rest of your team as collaborators as a "Group Submission".
Your final write-up is required to be between 6 - 8 pages using the
structured like a paper from a computer vision conference (CVPR, ECCV, ICCV, etc.).
Please use this template so we can fairly judge all student projects without worrying about
altered font sizes, margins, etc. After the class, we will post all the final reports online
so that you can read about each others' work. If you do not want your writeup to be posted
online, then please let us know via the project registration form.
The following is a suggested structure for your report, as well as the rubric that we will
follow when evaluating reports. You don't necessarily have to organize your report using
these sections in this order, but that would likely be a good starting point for most projects.
Refer to [Piazza] for more fine-grained details and explanations of each separate section.
Abstract: Briefly describe your problem, approach, and key results. Should be no more
than 300 words.
Describe the problem you are working on, why it's important, and an overview of your results
Related Work (10%):
Discuss published work that relates to your project. How is your approach similar or different
Describe the data you are working with for your project. What type of data is it? Where did it
come from? How much data are you working with? Did you have to do any preprocessing, filtering,
or other special treatment to use this data in your project?
Discuss your approach for solving the problems that you set up in the introduction. Why is
your approach the right thing to do? Did you consider alternative approaches? You should
demonstrate that you have applied ideas and skills built up during the quarter to tackling
your problem of choice. It may be helpful to include figures, diagrams, or tables to
describe your method or compare it with other methods.
Discuss the experiments that you performed to demonstrate that your approach solves the
problem. The exact experiments will vary depending on the project, but you might compare
with previously published methods, perform an ablation study to determine the impact of
various components of your system, experiment with different hyperparameters or architectural
choices, use visualization techniques to gain insight into how your model works, discuss
common failure modes of your model, etc. You should include graphs, tables, or other figures
to illustrate your experimental results.
Summarize your key results - what have you learned? Suggest ideas for future extensions
or new applications of your ideas.
Writing / Formatting (5%)
Is your paper clearly written and nicely formatted?
Supplementary Material, not counted toward your 6-8 page limit and submitted as
a separate file. Your supplementary material might include:
Source code (if your project proposed an algorithm, or code that is relevant and important
for your project.).
Cool videos, interactive visualizations, demos, etc.
Examples of things to not put in your supplementary material:
The entire PyTorch/TensorFlow Github source code.
Any code that is larger than 10 MB.
A computer virus.
You will submit your final report as a PDF and your supplementary material as a separate PDF
or ZIP file. We will provide detailed submission instructions as the deadline nears.
Additional Submission Requirements:
We will also ask you do do the following when you submit your project report:
Your report PDF should list all authors who have contributed to your work; enough to
warrant a co-authorship position. This includes people not enrolled in CS 231N such as
faculty/advisors if they sponsored your work with funding or data, significant mentors (e.g.,
PhD students or postdocs who coded with you, collected data with you, or helped draft your
model on a whiteboard). All authors should be listed directly underneath the title on your PDF.
Include a footnote on the first page indicating which authors are not enrolled in CS 231N. All
co-authors should have their institutional/organizational affiliation specified below the title.
If you have non-231N contributors, you will be asked to describe the following:
Specify the involvement of non-CS 231N contributors
(discussion, writing code, writing paper, etc). For an example, please see the author
contributions for AlphaGo (Nature, 2016).
Specify whether the project has been submitted to a peer-reviewed conference or journal.
Include the full name and acronym of the conference (if applicable). For example: Neural
Information Processing Systems (NIPS). This only applies if you have already
submitted your paper/manuscript and it is under review as of the report deadline.
Any code that was used as a base for projects must be referenced and cited in the body of the paper.
This includes CS 231N assignment code, finetuning example code, open-source, or Github
implementations. You can use a footnote or full reference/bibliography entry.
If you are using this project for multiple classes, submit the other class PDF as well.
Remember, it is an honor code violation to use the same final report PDF for multiple classes.
In summary, include all contributing authors in your PDF; include detailed non-231N co-author
information; tell us if you submitted to a conference, cite any code you used, and submit your
dual-project report (e.g., CS 230, CS 231A, CS 234).
Final Presentation (video recording)
We will not hold a poster session this quarter. Instead we will use video recording as the way for student to present and share their project. Each group is required to submit a 5-minute presentation video for their final project. Students can be as creative as they like for their video presentations. The easiest option is to create a slide deck together as a team and record yourselves presenting the slide deck as a group using zoom. Each student member should speaker during the presentation.
The following is a suggested structure for the video presentation. The specific rubric will be updated later in the quarter. You don't necessarily have to organize your presentation using these sections in this order, but that would likely be a good starting point for most projects.
Problem Statement: Briefly describe the problem your group is tackling. Describe the overall motivation, as well as the input / output of the problem.
Technical Challenges: Briefly describe why the problem is technically challenging.
Related Works: Briefly in what ways previous works have tackled the technical challenges.
Your Approach and Results: Describe your detailed technical approach and innovations. Describe evaluation results (dataset and metric).
Broader Impact: How do you expect the impact of your work to be? What can others learn from it or how can they apply it to solve their problems? What are the limitations of your work? What are areas for future improvements?
