Unverified50% confidenceBenchmarkExact time
Between NPU training and GPU training, the loss trajectory correlation coefficient reaches 0.99, which measures the similarity of training dynamics and does not mean throughput parity or that speed can catch up with GPUs.

VerifiedTechniques such as mixed-precision training and gradient accumulation enable training of larger models under limited GPU memory.73% similarUnverifiedThe reason for using a correlation coefficient rather than simply comparing final loss values is that it can capture the dynamic consistency across the entire training run, which proves the numerical validity of the training process better than a single endpoint metric.73% similarUnverified对于Vision AI项目，GPU训练时间往往是比订阅费用更大的成本项，减少无效训练轮次可能使综合投入产出比更优72% similarUnverifiedAfter adding the DINO objective, CAPI's originally smooth training loss curve became noticeably more erratic, and training stability decreased.70% similarUnverifiedThe 0.9999 consistency mentioned in the article refers to the numerical correlation coefficient or cosine similarity between the LoRA weights trained on the NPU and the weights trained with standard PyTorch under the same data and hyperparameters, not the accuracy of the model's final task.70% similar
