UnverifiedInference in diffusion models is an iterative denoising process that typically requires dozens or even hundreds of timesteps and is particularly sensitive to numerical errors.76% similarUnverifiedHigh bias means the model is too simple and leads to underfitting, while high variance means the model has learned noise and leads to overfitting, and the two tend to trade off against each other.74% similarUnverified越强大的模型其发布前的安全审查周期反而越长，延期有时是主动选择而非能力不足71% similarVerifiedThe three main causes of hallucinations in large models are training data noise, the probability-first mechanism, and insufficient data timeliness.71% similarUnverifiedThe iterative denoising process of diffusion models is sensitive to numerical errors; small errors at each step accumulate and affect the final image, and the more sampling steps there are, the greater the impact of quantization errors.70% similar
