- › LeWorldModel: Stable End-to-End Joint Embedding Predictive Architecture from Pixels LeWM learns end-to-end world models from pixels using JEPA with a single SIGReg regularizer — no reconstruction loss, no pretrained features, no temporal smoothness loss. Achieves 96% success on Push-T (vs 78% PLDM, 81% DINO-WM) with ViT-S predictor. Key insight: isotropic Gaussian latent constraint (SIGReg) replaces multiple regularizers; temporal straightening emerges implicitly. Jul 19, 2026
- › VL-JEPA: Joint Embedding Predictive Architecture for Vision-Language VL-JEPA learns a joint vision-language embedding space using only JEPA-style latent prediction + SIGReg regularization — no contrastive loss (CLIP), no generative loss (LLaVA), no reconstruction (MAE). Competitive zero-shot on ImageNet, Flickr30K/COCO retrieval, GQA/VQAv2 VQA. Jul 19, 2026
- › Attention Is All You Need — Paper Breakdown The Transformer replaces RNNs/CNNs with pure attention. Encoder-decoder stacks of self-attention + FFN achieve SOTA translation (28.4 BLEU EN-DE, 41.8 EN-FR) at fraction of training cost. Introduces multi-head attention, scaled dot-product attention, sinusoidal positional encoding. Jul 15, 2026
