JEPA representation alignment depends on the training views

What the condition means

A Joint-Embedding Predictive Architecture predicts a hidden representation of another observation. The authors give a theorem for paired observations of the same scene and bounds when that condition fails. The claim has conditions; it does not establish that every large model learns the same world representation.

What the experiments compare

The authors report that their chosen views need fewer examples to reach comparable alignment than next-token prediction on the same corpus. They also demonstrate aligning separately trained encoders for image captioning. These are alignment and benchmark results, rather than a general comparison of assistant usefulness.
