GPT-3 training used the Adam optimizer (beta1 = 0.9, beta2 = 0.95), gradient clipping to 1.0, a learning rate warmed up over 375 million tokens then cosine-decayed to 10% of its peak over 260 billion tokens, and weight decay of 0.1.

UnverifiedTaking GPT-3's attention layers as an example, the original weight matrix is approximately 12,288×12,288 (about 150 million parameters), while a LoRA decomposition with rank r=8 requires training only about 200,000 parameters, a compression ratio exceeding 700×.68% similarUnverifiedWhen DINOv3 ViT-H+/16 is pruned to 50% sparsity, removing 427 million parameters, ImageNet-1k linear probe accuracy drops by only 0.8%, without weight correction or retraining.67% similarUnverifiedThe milestones publicly demonstrated by VKORE include: training a 46-million-parameter model from scratch, running on 32 inference-only NPU chips, with a loss correlation of 0.99 with a GPU training baseline.66% similarUnverifiedThe author's fine-tuning used the QLoRA method, with LoRA rank/alpha of 32/64, a learning rate of 1e-4, batch size 1 with gradient accumulation of 16, AdamW 8-bit optimizer, and training for 1 epoch.66% similarUnverifiedOnce GOOSE is included in the training set, all augmentation branches perform within ±1 point of the control group on real weather, while augmentation still adds 3.5 to 5.2 points on synthetic held-out degradations.66% similar
