UnverifiedIn LoRA, matrix A is initialized with random Gaussian values and matrix B is initialized to zero, ensuring that the added quantity is zero at the start of training so as not to damage the original model's capabilities, and introducing no additional latency during inference.78% similarUnverified指令微调不需要从头训练，通常仅需基础训练计算量的1%以下即可显著改变模型行为模式78% similarUnverifiedOn small datasets, DETR weights pre-trained on large-scale datasets such as COCO should be used for fine-tuning rather than training from scratch77% similarPartially VerifiedA pre-trained model refers to a model that has been trained in advance on large-scale datasets, which users can directly fine-tune or call to complete specific tasks.77% similarUnverifiedPre-train & Fine-tune is the core training paradigm for current large models; after pre-training completes general knowledge learning, the fine-tuning phase requires only a small amount of data and computational resources to adapt to different tasks.76% similar
