Can regularization based JEPA (e.g. SIGReg) scale and compete with SOTA foundation models (DINO)? Here is the answer: yes and with 10x less data. VISReg (slight variation of SIGReg) competes with DINOv2-LVD142M while only training on inet22k. Try it out: https://t.co/vBhrNAmFq6 https://t.co/XERFZEAE8t

You definitely need to try our new work: VISReg!\n\nWhat does it achieve?\n💪 Strong collapse prevention: High gradient when embedding collapse\n⚡ Friendly to scale training: Linear complexity to scaling factors\n🧩 Easy to train: Similar to LeJEPA, it is a heuristic-free method\n🏆 Best OOD performance: Achieving the best accuracy on 6 OOD datasets\n📉 Data efficiency: Achieving a similar OOD average accuracy to DINOv2 with 90% less data\n🧬 Robust to low-quality datasets: It is robust to long-tailed and sparse datasets\n\nOur results also indicate that SIGReg type methods can scale up, filling in the missing piece in @ylecun's great talk https://t.co/P9TXmk3fFa.\n\nA big thanks to my co-author @randall_balestr and my manager @DrMorganLevine. Also, huge gratitude to @ylecun for connecting us to make this project happen! 🤝\n\n#SelfSupervisedLearning #JEPA #WorldModel",
