In this series, we'll explore the complex landscape of machine learning and artificial intelligence through one example from the field of computer vision: using a decision tree to count the number of fingers in an image. It's gonna be crazy.

Big thank you for Yann’s collaborator Randall Balestriero for discussing JEPA at length with me, Randall’s his recommended reading:
- LeJEPA for more theory on why isotropic Gaussian and details on SIGReg: https://arxiv.org/abs/2511.08544
- connection between SSL and spectral embedding (very useful to understand the geometry learned by those models): https://arxiv.org/abs/2205.11508
- LeWorldModel (world model version of LeJEPA): https://arxiv.org/abs/2603.19312
- identifiability theory of LeWorldModel (fresh out of the oven): https://arxiv.org/abs/2605.26379
- and perhaps most important of all, the reason why one should use JEPA and not reconstruction based learning: https://arxiv.org/abs/2402.11337 and https://arxiv.org/abs/2505.12477

Technical note about VL-JEPA embeddings. The VL-JEPA team used a SONAR decoder/encoder, which works at the sentence level instead of the token level for the controlled VLM/JEPA comparisons.
