Humans have a spontaneous ability to process raw visible signals from the retina and develop a structured understanding of their surroundings, identifying objects and motion patterns. A major goal of machine learning is to highlight the underlying principles that enable such unsafe human education. A major hypothesis, the future characteristic theory, suggests that the representation of frequent sensory inputs should be predicted by each other. Early methods, including slow facility analysis and spectral techniques, aims to maintain temporary stability to prevent representation collapse. The more recent approaches include the Siami network, contrast learning and masked modeling to ensure meaningful representation development over time. Instead of fully focusing on Temporal Inverterion, modern technologies train predetermined network to map the relationship in different time stages, use frozen encoders or train both encoders and prophet together Are. This future-staging structure has been successfully implemented in methods such as images and audio, such as models such as Jepa take advantage of joint-ambeding architecture, which effectively predict the missing feature-space information.
Progress in self-levied learning, especially through vision transformer and combined-ambeding architecture, has improved considerably in masked modeling and representation. Spatiotemporal Masking has increased these reforms into video data, increasing the quality of learned representatives. Additionally, cross-qa-lying-based pooling mechanisms have refined masked autoencoders, while methods such as biol reduce representation down without relying on handcrafts promotion. Compared to pixel-space reconstruction, prediction in feature space allows the model to filter irrelevant details, leading to efficient, adaptable representations that are well common in functions. Recent research states that this strategy is computically efficient and effective in domains such as images, audio and lessons. This task extends these insight to the video, showing how the future feature is increased the repatriate republic representation quality.
Researchers of the fair at Meta, INRIA, école Normale Supérieure, CNRS, PSL Research University, Univ. The Gustav Eiffel, the Cortecent Institute, and the University of New York introduced the V-JEPA, a vision model was trained on the feature prediction for specially uncontrolled video learning. Unlike traditional approaches, the V-JEPA does not depend on pretrand encoders, negative samples, reconstruction or text supervision. Trained on two million public videos, it receives strong performance on speed and appearance-based tasks without tuning. In particular, the V-JEPA performs better in some other ways on some other ways on some-V2 and remains competitive on the Kinetics-400, it displays that the future prophecy alone alone is efficient and adaptable visual representation with low training periods Can produce
The functioning involves training a foundation model for object-centered learning using video data. First, a nervous network represents object-focused from video frames, capturing signs of speed and appearance. These representations are then refined through opposite learning to increase object separation. A transformer-based architecture processes these representations to model object interactions over time. The framework is trained on a large scale dataset, which adapt to the reconstruction accuracy and stability in the frame.
The V-JEPA is compared to the pixel prediction methods using the same model architecture and shows better performance in video and image functions in frozen evaluation, except for imagenet classification. With fine-tuning, it improves the WIT-L/16-based model and corresponds to Hyra-L during the requirement of low training samples. Compared to state-of-the-art model, V-JEPA excels in understanding and video functions, training more efficiently. It displays strong label efficiency, improves contestants in low-shot settings by maintaining accuracy with low-label examples. These results highlight the benefits of facilities in learning effective video representations with low computational and data requirements.
Finally, the study examined the effectiveness of feature prediction as an independent purpose for unheard video learning. This introduced the V-JEPA, which is a set of purely trained vision models through self-altitude features prediction. The V-JEPA parameter performs well in various image and video functions without the need for adaptation, crosses the previous video representation methods in the frozen evaluation for action recognition, spatyotamporel action detection and image classification. Pretraying on the video enhances its ability to capture the right-untouchable speed details, where large-scale image models struggle. Additionally, the V-JEPA displays strong label efficiency, even when the limited label data is available for downstream functions, maintains high performance.
