UnverifiedSmaller models are more prone to embedding collapse than larger models, due to reasons including limited parameter capacity, a tendency toward optimization shortcuts, and amplified anisotropy issues.71% similarUnverified自回归生成的误差累积效应源于模型只能沿单一路径前进，误差以乘积形式放大70% similarUnverifiedAcceleration solutions such as consistency models and flow matching are narrowing the computational overhead gap of multi-step inference in diffusion models.70% similarUnverified聚合多个基准的评测方式降低了单一基准被针对性优化（刷榜）的风险69% similarUnverifiedThe optimal regularization strength needs to be selected through cross-validation; if it is too large it leads to underfitting, and if it is too small the regularization effect is negligible.69% similar
