The topic of this year's computer lab is deep learning. The lab is carried out in groups of two students. To pass the course, you must pass the computer lab. No written report is required, but you need to come to the lab session, work actively on the material and complete the lab to pass. The lab is graded (U/G) based on the students presenting their solutions to the teacher at the end of the lab session. The mandatory preparatory exercises must be completed and submitted on Studium before the fist scheduled lab session.

Important Deadlines:

• 21st of February: Sign up to a lab group

• 28th of February 08.00 am: Submit your solutions to the preparatory exercises.

The goal of this laboratory work is to:

• Learn how to build and train a neural network
• Learn how to improve the neural network model and its training.
• Application 1: Learn how to classify hand-written digits using neural networks.
• Application 2: See how a state-of-the-art deep neural network performs at classifying real-world images
• Get a glimpse of a state-of-the-art software library (PyTorch) for deep learning.

The lab instructions and other lab material can be found at the bottom of this page. You are welcome (and recommended) to start looking at the lab material before the lab session. This will make the lab session more efficient. If you complete the lab before the lab session, you can come to the session simply to present your solutions to the teacher.

Lab groups:

Make sure you sign up to the session you wish to attend. The schedule is as follows:
Group 1-15: Mon 28/2 08.00 - 11.45 ZOOM
Group 16-35: Tue 1/3 08.00 - 11.45 ZOOM
Group 36-55: Tue 1/3 13.00 - 16.45 ZOOM
Group 56-70: Wed 2/3 13.00 - 16.45 CAMPUS
Group 71-85 Thu 3/3 13.00 - 16.45 CAMPUS
Group 86-100 Tue 8/3 08.00 - 11.45 ZOOM

Preparatory exercises:

1. Read Chapter 6 and Section 5.4 in the SML course book.

2. Read Chapter 1 and 2 in the lab instructions. If you are new to PyTorch, have a look at the Introduction to PyTorch notebook before the lab session. Reading and running the notebook is highly recommended, since it introduces important concepts and commands that are required in the lab session. The instructions and introduction notebook can be found at the bottom of this page.

3. Read Chapter 3 in the lab instructions. Solve the preparatory exercises found in this chapter and submit your solutions on Studium. You can discuss the preparatory exercises with other students, but each student must submit their own solutions. The deadline for submitting the solutions to the preparatory exercises is on the 28th of February 08.00 am. Submit your solutions here.

Installation:

PyTorch is already installed on the Linux systems in the computer rooms where the laboratory session is scheduled. You can either use these computers during the lab or bring your own computer. If you choose to use your own computer, you need to have PyTorch properly installed before the lab. The lab assistants will not be able to assist you with the installation process during the lab. Please consult the PyTorch documentation for more information about the installation procedure. Another option is to use Google Colab to work with PyTorch online. This cloud platform also optionally provides access to GPUs which might speed up some computations.
