A new paper by Randall Balestriero and Yann LeCun argues that paired-view training (e.g., image-caption pairs), not sheer scale or next-word prediction, is what produces unified world representations—showing a 109M-parameter model outperforming a 72B language model in representational alignment.
Yann LeCun and Randall Balestriero mathematically prove the Platonic Representation Hypothesis and show that JEPA training with scene-related positive views achieves image-text alignment with 42× less data, with a 109M-parameter text JEPA outperforming LLMs up to 72B on cross-modal benchmarks.
论文提出 AC-JEPA(Anchored Cross-Modal JEPA),一种可与 SFT 兼容的即插即用模块,通过在双向跨模态预测掩码中间表示来提升视觉到符号序列的翻译能力。在光学化学结构识别(OCSR)任务上,AC-JEPA 在 WildMol Simple 上达到 76.07% 准确率(基线 SFT 为 67.40%),并在使用含噪声伪标签数据自训练时提升至 80.23%,而直接 SFT 反而性能下降。
The paper introduces Variational Atlas Autoencoders, a mixture-of-charts framework that learns multiple local latent representations over a data manifold, using latent-evidence routing to treat chart assignment as self-supervised posterior inference, achieving better-structured latent spaces and higher sample quality on datasets like CelebA.
The paper proposes 'predictive closure,' a set-level characterization of how JEPA selects features to encode, showing that feature retention depends on relationships within feature sets rather than individual predictability, with experiments demonstrating that unpredictable features can be preserved when they aid prediction of others.
The paper introduces a self-supervised representation learning framework that uses temporal proximity as supervision to learn compact representations from short-term animal movement trajectories, showing they reveal individual identity and learning progress in freely behaving rats.
该论文提出一种噪声鲁棒的强制对齐方法,用上采样WLM特征替代MFCC的GMM-HMM对齐器,并显式建模填充词和非词汇语音事件,在Buckeye和FluencyBank上将词边界误差降低19%和17%,大幅减少灾难性错配。
PhysSkin++ introduces a physics-informed framework that learns continuous neural skinning fields from static geometries, enabling real-time, generalizable physics-based animation across diverse shapes and spatial representations without per-object training.
The paper identifies a theoretical incompatibility between 3D point cloud masked autoencoding and SE(3)-equivariant networks, proving that standard masking triggers a topological collapse, and introduces SIEVE, an equivariant self-supervised framework using a spherical projection mask to preserve global pose while obfuscating local semantics, improving downstream generalization to unseen shape categories.
