Unverified贝叶斯推断、最大似然估计、KL 散度等概率统计概念在现代生成模型（如 VAE、Diffusion Model）中广泛应用74% similarUnverifiedWhen prepending is applied to models such as Kimi and GLM, the distribution of reasoning length undergoes a statistically significant shift and aligns toward a certain source model.72% similarUnverifiedThe theoretical foundation of diffusion models was unified by Song Yang et al. in 2020 through a stochastic differential equation (SDE) framework; the discovery of probability flow ODEs enabled deterministic sampling and gave rise to accelerated sampling methods such as DDIM, compressing the number of sampling steps from 1000 to 10–50.72% similarUnverifiedLLM可通过分析输出token的对数概率分布、思维链末尾自我评估、温度采样统计答案分布熵值等手段近似估计决策置信度71% similarVerifiedThe essence of LLMs is statistical probability-based sequence prediction rather than true logical reasoning, which creates inherent limitations when handling long-context dependencies, global architectural consistency, and complex edge cases.69% similar
