Assignment Overview
Welcome to Homework 7! You'll start this assignment by building a logistic regression model, then learn how to calculate gradients automatically and explore neural networks using the PyTorch library, gaining hands-on experience with the deep learning pipeline. Here's what you'll learn and explore:
- Fundamentals of logistic regression
- Backpropagation with PyTorch
- Building basic neural networks with PyTorch
PyTorch
Important: For this assignment, you will need to install PyTorch, a deep learning library. We avoided installing PyTorch during the HW0 setup so that the environment setup was straight forward and Torch can be a bit finicky to install.
If you run into issues installing torch, you can run this notebook (and any future notebooks that will run Torch) in Google Colab without any additional setup work.
To install torch, you should activate your environment and run: pip install torch==2.3.0
Downloads
Like Homework 5, this assignment will take place in a Python notebook file.
Please click here to download the assignment code.
If you get a message "Running cells with 'cs410_env (Python 3.10.6)' requires the ipykernel package," please install the package.
Handin
Your handin should contain:
- all modified files, including comments describing the logic of your algorithmic modifications
- a README, containing a brief overview of your implementation
Gradescope
Submit your assignment via Gradescope.
To submit through GitHub, follow these commands:
git add -Agit commit -m "commit message"git push
Now, you are ready to upload your repo to Gradescope.
Tip: If you are having difficulties submitting through GitHub, you may submit by zipping up your hw folder.
Rubric
| Component | Points | Notes |
|---|---|---|
