- pico-JEPA: ultra-light JEPA models combined by voting
- nano-JEPA: a video JEPA you can train on a personal computer
- nano-datasets: builds small custom subsets of large video datasets
Video summarization¶
- Flash Video Summarization: summarization that runs faster than real time
- Open Summarization Toolbox: evaluation tools in Python and C++
- OST datasets: datasets widely used in video summarization research
Optimization and parallel computing education¶
