Researchers have developed a new method called the Frame Forgetting Network (FFN) to improve Test Time Training (TTT) for long videos. Existing TTT methods struggle with the computational demands of processing hours-long videos and performing updates on redundant frames. The FFN addresses these issues by operating on only three frames at a time and introducing a 'surprise metric' to adaptively adjust the processing window based on new information content. This approach allows for efficient adaptation to long videos, demonstrated on tasks like dense segmentation and video classification, and is supported by a new dataset, EpicTours, featuring up to three-hour videos.
