Piazza and Canvas

All course communication will happen via Piazza and Canvas. All videos will be posted to Canvas for offline viewing though aspects of the class/teaching will be interactive and missing from the zoom sessions. Questions will be taken in person -- not on chat

Piazza: https://piazza.com/cmu/spring2023/11777

Assignments Timeline and Grading

The course is primarily project based, but there will be readings throughout the course which are only graded via participation.

Project Timeline and Assignments (70% total): (see links for more details)
Jan 30 Submit group members (see Piazza)
Feb 14 R1 Dataset Proposal and Analysis (10%)
Mar 03 R2 Related Work and Model Proposal (15%)
Mar 31 R3 Baseline Analysis (15%)
Apr 25/27 Presentation (10%)
May 1 R4 Completed Report (20%)

Discussion Participation (20%, with up to 2% bonus):
We will have discussion posts for papers and lectures on Piazza. We ask you to make two thoughtful contributions per week (either asking questions or posting answers) on these posts. 11 weeks x 2 contributions = 22pts, but we will grade out of 20 points allowing for 2pts of extra credit. We also will give credit for asking questions in lectures.

Paper Summaries (10%):
Writing a three sentence summary describing the paper you read earns you 1pt. This summary will be submitted in three text boxes. Specifically, A. The goal of the paper, B. Explain the key insight, C. State a key limitation or important extension. There will be 11 opportunities, so one bonus point can be earned (11%). Paper summaries are due the following Tuesday night (1 week after being assigned).

Submission Policies:

Tasks & Datasets

The course will be primarily centered on a few datasets/tasks to facilitate cross-team collaboration and technical assistance. If your team has a good reason to work on something else, please reach out so we can discuss it and put together a proposal.

ALFRED Code Embodied instruction following with interaction

Question Answering & Captioning
TextVQA Code Text in images (referring expressions and reading)
WebQA Code Multihop Visual QA
VizWiz VQA and Captioning Visual models for blind users

Physical hardware / robots / sensors ...
What about physical hardware? robots? tasks not datasets? Let's talk.

Compute Limited AWS compute credits will be made available to each student, so please consider both your interests and available compute resources when deciding on a dataset/project.
