What is the V-JEPA model?

V-JEPA model is an exclusively trained vision model which is created using the feature prediction objective. It plays a vital role in understanding the advanced machine intelligence which will imitate the process of human learning. V-JEPA understands and learns directly from the videos without any external supervision.

Video Joint Embedding Predictive Architecture (V-JEPA) model is embodied of LeCun’s theory. It is featured to develop the World’s internal conceptual model. V-JEPA model is a trained AI model which could also lead towards a change in the world of AI models. Meta said that they released the V-JEPA model under the noncommercial license of Creative Commons which will help the researchers to conduct experiments with the model as well as  expand the model’s capabilities.

What is the I-JEPA model?

The I-JEPA (Image Joint Embedding Predictive Architecture) model, introduced by Yann LeCun, Meta’s Chief AI Scientist, is a major breakthrough in AI. The goal of this approach is to give machines a capability to create internal models of how the world works, perform complex tasks, and adapt to unseen circumstances more efficiently.

It is trained using self-supervised learning and has the ability to learn competitive off-the-shelf image representations without the need of extra knowledge that is externally encoded through hand-crafted image transformations. The I-JEPA model’s work was presented at CVPR 2023, and the training code and model checkpoints are open-sourced, paving the way for further exploration and collaboration in the AI community.

Features of the I-JEPA model

The I-JEPA (Image-based Joint-Embedding Predictive Architecture) model by Meta has a number of important characteristics in self-supervised learning from images. 

  • It fills the missing information using predictions based on abstract prediction targets and as a result, the model is able to learn more semantic features.
  • Unlike many other computer vision models used today, the I-JEPA model is more computationally efficient, needing fewer computing resources during training.
  • The model beats the other state-of-the-art models on computer vision tasks like classification, object counting and depth prediction, showing its high performance and effective use in different tasks.
