DSCI 572: Supervised Learning II

Welcome to Supervised Learning II! In this course, we delve into the world of deep learning using Python and PyTorch. You'll learn about optimization, the fundamentals of neural networks, and convolutional neural networks. We'll also explore some advanced topics such as generative adversarial networks.

By the end of this course, you will be able to:

Identify common computational issues caused by floating-point arithmatic, e.g., rounding, overflow, etc., and program defensively against these errors.
Explain how the gradient descent algorithm and its variants work.
Explain the fundamental concepts of neural networks including layers, nodes, and activation functions and gain proficiency in implementing basic neural networks using PyTorch.
Illustrate the process of backpropagation in neural network training.
Explain how convolutional neural networks work and implement them for image classification using PyTorch.
Explain and apply transfer learning and the different flavours of it: "out-of-the-box", "feature extractor", "fine tuning".
Describe at a high level the basic principles and architecture of Generative Adversarial Networks (GANs)

Lectures

Format

I strongly recommend reviewing the corresponding lecture notes before each lecture. During the lectures, I will focus on the key concepts. It's also highly advised to download the relevant datasets and run the lecture Jupyter notebooks on your own. Experimenting with the code will greatly improve your understanding.

Lecture schedule

This course occurs during Block 4 in the 2023/24 school year.

#	Topic	Resources and optional readings
1	Floating Point Errors	Floating Point Arithmetic: Issues and Limitations
2	Optimization and Gradient Descent
3	Stochastic Gradient Descent
4	Introduction to Neural Networks & PyTorch
5	Training Neural Networks
6	Convolutional Neural Networks Part 1	Stanford cs231 CNNs notes
7	Convolutional Neural Networks Part 2
8	Advanced Deep Learning

Installation

We are providing you with a conda environment file which is available here. You can download this file and create a conda environment for the course and activate it as follows.

conda env create -f dsci572env.yml
conda activate 572

In order to use this environment in Jupyter, you will have to install nb_conda_kernels in the environment where you have installed Jupyter (typically the base environment). You will then be able to select this new environment in Jupyter. If you're unable to see the environment in Jupyter, you might have to install the kernel manually. See the documentation here. For more details on this, refer to your 521 lecture 7.

I've only attempted to install this environment file on a few machines, and you may encounter issues with certain packages from the yml file when executing the commands above. This is not uncommon and may suggest that the specified package version is not yet available for your operating system via conda. When this occurs, you have a couple of options:

Modify the local version of the yml file to remove the line containing that package.
Create the environment without that package.
Activate the environment and install the package manually either with conda install or pip install in the environment.

Note that this is not a complete list of the packages we'll be using in the course and there might be a few packages you will be installing using conda install later in the course. But this is a good enough list to get you started.

Course communication

We are all here to support your learning and success in the course and the program. Here's how our communication will work during the course.

Clarifications on the lecture notes or lab questions

If there is any clarification on the lecture material or lab questions, I'll post a Slack message on our course channel and tag you. It is your responsibility to read the messages whenever you are tagged. (I know that there are too many things for you to keep track of. You do not have to read all the messages but please make sure to carefully read the messages whenever you are tagged.)

Questions on lecture material or labs

If you have questions about the lecture material or lab questions, please post them on the course Slack channel rather than direct messaging me or the TAs. Here are the advantages of doing so:

You'll get a quicker response.
Your classmates will benefit from the discussion.

When you ask your question on the course channel, please avoid tagging the instructor unless it's specific for the instructor (e.g., if you notice some mistake in the lecture notes). If you tag a specific person, other teaching team members or your colleagues are discouraged to respond. This decreases the response rate on the channel.

Please use some consistent convention when you ask questions on Slack to facilitate easy search for others or future you. For example, if you want to ask a question on Exercise 3.2 from Lab 1, start your post with the label lab1-ex2.3. Or if you have a question on lecture 2 material, start your post with the label lecture2. Once the question is answered/solved, you can add "(solved)" tag before the label (e.g., (solved) lab1-ex2.3. Do not delete your post even if you figure out the answer on your own. The question and the discussion can still be beneficial to others.

Questions related to grading

If you have concerns related to grading:

First, ensure that you have thoroughly reviewed your response, our solution key, and any TA feedback.
Verify that your concerns align with our 'Reasonable grading concerns' policy, which you can read here.

If you believe your concerns are valid:

For assignments: Submit a regrade request on Gradescope.
For quizzes: Directly message the TA responsible for grading that question. (I will inform you on Slack who has graded what after grades are returned.)
If you cannot resolve the issue with the TA, send a Slack message to the instructor, including the relevant TA in the conversation.

Questions related to your personal situation or talking about sensitive information

I am open to having a conversation with you. If you'd like to discuss any sensitive matters, please send me a direct message on Slack (and mention/tag me) instead of posting it in the course channel. It may take some time for me to respond, but I'll make every effort to reply as promptly as I can. If I cannot address your issue directly, I can at least direct you to the appropriate person who may be able to assist you.
