Joint embedding predictive architecture

NettetWe introduce the Image-based Joint-Embedding Predictive Architecture (I-JEPA), a non-generative approach for self-supervised learning from images. The idea behind I-JEPA is simple: from a single context block, predict the representations of various target blocks in the same image.

Nettetcently proposed Joint Embedding Predictive Architectures (JEPA) [20] offer a reconstruction-free alternative. In this work, we analyze performance of JEPA trained with VICReg and SimCLR objectives in the fully offline setting without access to rewards, and compare the results to the performance of the generative architecture. Nettet5. mar. 2024 · In this work, Microsoft Dynamics 365 AI Research’s UNITER model focuses on learning a generalizable joint embedding for images and text. The UNITER model architecture (from top to bottom) UNITER uses self-supervised learning on a lot of data, like BERT, to ensure that the learned embeddings are generic.

The idea behind I-JEPA is simple: from a single … NettetThe centerpiece of the proposed architecture is a configurable predictive world model that allows the agent to plan. Behavior and learning are driven by a set of differentiable intrinsic cost functions. The world model uses a new type of energy-based model architecture called H-JEPA (Hierarchical Joint Embedding Predictive Architecture).

NettetThis brings us to the star of the paper: the Joint Embedding Predictive Architecture (JEPA). JEPA is a SSL energy-based model (EBM) that captures the dependencies between two given inputs, say x and y. Let’s go through an example of applying JEPA to a recommendation task (this is Shaped’s blog after all 😉). Nettetcently proposed Joint Embedding Predictive Architectures (JEPA) [20] offer a reconstruction-free alternative.
