Internship | Video-RAG for Activity Recognition

Retrieval Augmented Generation (RAG) has advanced the use of LLMs, by contextualizing the predictions with fact-based guidance. The power of RAG is recently also explored for computer vision. From a large set of images, called the memory, a subset is selected to guide the predictions for the current test sample. This selection from memory is conditioned on the test sample. We believe that RAG can also be powerful for human activity recognition. More complex activities typically extend over a longer time period. For instance, a person taking an object after putting another object down. See Wu et al 2021 for a dataset with more examples, e.g. Which object did the person take after they put down the bottle? (A) Book. (B) Towel. (C) Phone. (D) Table. The long duration makes it hard to put all video frames simultaneously into GPU memory. Although several researchers have come up with clever video frame aggregation strategies, we believe that RAG can be helpful to select and weigh the relevant video frames more carefully, conditioned on the hypotheses A-D. We can leverage vision-language models (VLMs) and advance them with RAG by cross-modal attention between the video frames (vision) and the hypotheses (language). How to devise such a cross-modal attention? How can we leverage the hypotheses to make better predictions? How well do the selected video frames correspond to the key moments in the long-term activity?

Explore the opportunities of RAG for long-term action recognition. Research how to express prior information about hypotheses in effective prompts. Research cross-attention mechanisms between the prompts and visual video contents, to efficiently aggregate key moments in the video. Investigate the key moments (explainable AI) for activity understanding.

You will perform this assignment within TNO’s Intelligent Imaging department.

After the first CV selection, the application process will be conducted by the concerning department. TNO will provide a suitable internship agreement. If you have any questions about this vacancy, you can contact the contact person mentioned below.

For this internship vacancy it is required that the AIVD issues a security clearance (VGB) after conducting a security screening. Take into account that this process may take about 8 weeks. If you have been abroad for more than 6 consecutive months, or if you do not have the Dutch nationality, it may take longer. Read more about security screening on the AIVD website.

Important to be aware of before applying:

• Before the start of the internship, the internship agreement from TNO needs to be signed. For students at a college or university based in the Netherlands, TNO uses the UNL-template (supplemented with a number of specific agreements from TNO). For students of foreign and MBO educational institutions, the TNO internship agreement applies. TNO does not sign any other internship agreements.
• Before the start of the internship, the educational institution will need to confirm in writing that:
  • 1) you are enrolled at the educational institution during the internship, and;
  • 2) the internship takes place as part of the programme of the study.
• The confirmation of educational institution takes place by signing the UNL template or forms prepared by TNO.
• Interns at TNO must be in possession of a Dutch residential address at the start of the internship. Performance of internship activities from abroad is not possible.
